dumbells was perfectly as expected and totally worth the relatively low price. Definitely well worth

My doctor recently advised me to add in some more strength training into my workout regimen. Currently it is mostly all cardio, but he recommended that at my age (almost 50) I need the strength training to help keep off weight and maintain bone strength. I hate going to gyms, so I decided to look into some home gear. I don't have a lot of space to set up a big system so the most I can pack into a smaller package the better. I decided to start with dumbbells since my upper body is neglected more than my legs and core since I mostly hike/bike/run. While the JAXJOX system is not cheap, it also isn't necessarily cheap to buy individual sets of dumbbells at different weights. I also am a data geek and want to be able to track my strength training workouts the way I do my cardio ones (plus I want to prove to my doc that I'm actually following his advice). Fair warning, your delivery driver is going to hate you. When my driver showed up at my door, he was a bit flustered. For being a relatively compact box, it weighs about 110lbs. Told him that it was a multiple weight dumbbell set and while he understood, I could definitely hear grumbling as he walked away. Everything is packed well in some nice high density foam so they were all in perfect shape once I got them unpacked. Set-up was easy, put the extra weight plates in each dock, slotted in the core weights, and plugged in the docks. I did run into a bit of a problem here in that the supplied USB-A to USB-C cables are maybe 3-4 feet in length, and where I wanted to set them up is not that close to a plug. They also do not supply a USB charging brick so I had to grab one of my own. I was happy to see that the docks take USB-C plugs because I have been trying to shift all my cables to that and I'm almost there with everything except my phones. With that said, I grabbed one of my newer charging bricks that had two slightly longer USB-C to USB-C cables attached. Plugged them in and.... nothing. The dumbbells would not wake up or charge. Tried a bunch of things but nothing worked. Finally, I dug out an older USB-A charger and used the supplied cables after moving the weights closer to a plug. What do you know, that was the problem. You can not use a high power charging brick with these. Either that or they didn't like the cables. Try to stick with the ones that come in the box if you can. Next, I fired up the JaxJox app that I had already downloaded to my phone and synced the dumbbells up. They connected fairly fast and once I was done tinkering around a bit in the app, I let the dumbbells and the dock charge up for the night. Here is where I ran into my first minor problem. At about 10pm, right when I'm getting ready to go to sleep, I hear a beep. It is pretty quiet in the house and I have the windows open so I'm not sure where it came from but now I can hear it about every 15 seconds or so. I head downstairs and see that one of the docks has its screen lit up and it shows that the dock is almost finished charging. What I don't understand is why it has to beep. The other base was fully charged and it didn't beep. So I picked up the core dumbbell and re-seated it into the dock to see if that would help, and that seemed to have done the trick, but then about a minute later it did it again. The only way I was able to get it to stop was to unplug them. The charge has lasted the last five or so days, so I don't think they have to be plugged in the whole time, but be aware of this if you do. My first workout was a pretty straightforward one of multiple sets of arm curls just to see how the tracking software works. The software did a good job tracking the number of reps but for some reason it counted more sets than what I did. I couldn't find any default number of reps that equals a set nor could I find a way to set my own. I'm still working on figuring that one out. Either way, I completed my workout that morning, and did a few other workouts throughout that day and the next. I've never taken a fitness class before, unless you consider a drill instructor yelling at me to do more flutter kicks to be a fitness class! I decided to try the classes that are in the app. You get a free month of membership when you sign on so you can check out if they are for you or not. You can narrow your class choices by device (JaxJox makes other workout devices as well), they type of exercise, time, and teacher. I picked one with Coach Darsenio that was a 45 minute Dumbbell Circuit (it was the first one to pop up). I was able to cast the video and sound to my TV via AirPlay and we were off and running. Like literally. One of the first exercises was a high knee/arm curl exercise that mimicked running in place. Now he had us using just the core 8lb weight so it wasn't too bad but I could see this being a killer with more weight. I was surprised that he wasn't annoying. He didn't yell, and he didn't say I was doing a great job (even though they can't see you and for all they know I could be on my couch eating a pint of ice cream), which are two things that really bug me about other recorded/televised workouts I've seen advertised. I did not complete the entire 45 minutes, because I was not quite prepared for a workout of that length yet. The next day I did one of the 15 minute ones and added on some exercises of my own. Oh, I almost forgot to write about probably the most important feature of these dumbbells! The fact that you can change the weight on the dumbbells rapidly. With the core dumbbell on the dock you can raise and lower the weight of each dumbbell by 6lbs at a time (3lbs at each end). There are 14 plates on each dock (7 at each end) for a total combined weight of 50lbs if you max it out. It's easy to just hit the up and down buttons on each dock to change the weight and it takes just a second to two to make it happen. You can also use the app to change the weight, though I'm not sure how that would be easier than the docks since you have to be at the docks to change the weight anyway, but hey, you can if you want. I was a little afraid that the weights would rattle or move to0 much when doing the exercises but they are pretty stable on each dumbbell. I had read in a review prior to getting these that it was difficult to place the weight back into the dock because the plates lean in and block a smooth controlled drop into the dock, but I didn't find that to be the case. Whether JaxJox changed the plate configuration, or the other person set up theirs wrong, the plates stay vertical and in place so it is an easy slide into place when done with your workout or changing weights. If I had one major quibble with the JaxJox Dumbbell Connect system, it is that there is no stand for them. Well, there is, but it is part of their complete home gym system and not a standalone rack. It really could use one so that I don't have to go all the way to the ground to pick-up/change/drop the weights. Right now they are on a counter but that is a bit too high to be comfortable either. Other weight sets like these have a stand accessory, and I would appreciate JaxJox making one available as well. That, plus the little power/beeping issues take it down a star for me. Otherwise, this is a great home workout device that cuts down on clutter and provides a pretty decent app/workout experience.

I give 4 stars because sometimes its hard to mount the weights back in to the bases. Other than that easy to use and good quality.

These are just what I was looking for my home gym. They are good for someone new or want an adjustable on budget. They are quick to change weight, maybe about 10 secs max if going from 8lbs to 50 lbs. When using they feel secure since it is locked into place at the weight and there is the bar that goes through the middle.

These weights are pretty bulky, tho they work perfectly. Its pretty annoying to change them. Overall i don't love them but they do the trick when and cheaper than buying variations of weights.

The sliding mechanism stopped working. Will be returning these.

No good came with magnet not in one side of the weights and don’t latch good

These dumbells are really neat. Not only do they save space by being adjustable weight instead of having multiple sets of dumbbells, but the ability to use either the JaxJox app or just the buttons on the dumbbell racks to change the amount of weight is super easy. The dumbbells connect with the app to keep up with your sets, reps, and watts as you work out, and the app will keep up with your workouts to tell you how you are progressing. Pretty amazing. The app also has multiple classes available to give you guidance and keep you motivated. I highly recommend downloading the app before you purchase the dumbbells so you can get a sneak peek of what's available. The price of the dumbbells may seem expensive, but when you consider you would have to buy 8 sets of individual dumbbells to get the same range of weights, it's a no-brainer. One thing I would possibly consider before you were to buy these dumbbells is to check out their Interactive Studio package. You get the dumbbells on a stand, interactive kettlebell, interactive foam roller, and large screen to view classes/workouts. For some people it may be worth the extra money to upgrade to it. My only criticism is that the weights are not on a stand that would make them easier to pick up to start. Also, this would probably allow them to be charged together instead of having to plug them in individually. Overall I highly recommend.

I really like these. It was a lot of money, but well worth it. They work well and have improved my motivation to work out. I reviewed the alternatives and found this deal to be impressive. Highly recommend. I should add that I haven't utilized the app much.

Delivered as advertised but couldn’t get the app to work.

These are convenient and awesome. I am glad I made the purchase. Work perfectly and remember to use the app to change the weight of both of them at the same time

Terrible product Couldn’t get the dumbbells to work or switch weights

Dumbbell did not charge, wouldn’t recommend. …

I bought these for my son-in-law last Christmas and, just a couple ago, he was lying on the floor, holding the weights above his head, and 40 pounds of weights fell off towards his face. They no longer work now.

Two major issues that made it super hard to use: 1) The dumbbell relies on the internal battery to work, yes there is one battery in the base and the second battery in the dumbbell itself, and it is the latter that I am talking about. The internal battery would die probably in two weeks, which would make the entire set useless -- yes, you won't be able to change the weight after the battery dies, even if the base battery is still functioning. 2) the design of the dumbbell is not robust enough, so you almost always need to use two hands to accurately put each dumbbell back to its base, otherwise you'll easily find your dumbbell stuck at the base and won't change weight. So never expect to simultaneously put both dumbbells back and change weight. It won't work that way.

This was a great present for my daughter. She uses it for strength training. I have the JAXJOX kettle bell and love it. This was a gift she really loves and uses.

Awesome product. The ease of switching weights and the digital interface is cool. The app tracks the reps as well.

Staff was very helpful. Had product that my girlfriend was looking for in stock.

I really wasn’t sure what to expect with these as this is my first pair of smart dumbbells. The package came with 2 dumbbells, a docking mechanism for each dumbbell, weights you can attach to the sides of each dumbbell, and a charging cable for each docking station. It doesn’t come with a wall charger to plug the USB charging cables into the wall, so you’ll either have to use one you already have or buy one at the store. The attachable weights fit snuggly into either side of the dock, and the dumbbell goes in the center of each. Set up is very easy and shouldn’t take long. The dumbbells can reach a max weight of 50 lbs. and a minimum weight of 8 lbs. each, so keep that in mind if you’re looking for something heavier or lighter. Changing the weight sizes is easy; while the dumbbells and additional weights are in the dock, just use the arrows on the front of the dock to change the weight to a higher or lower setting. You can also do this in the app (more on that below). I haven’t used the dumbbells until they completely died and needed a charge, so I’m not sure how long the battery lasts. However, I use them for about an hour every day or two and they last for a few days before I decide to charge them again. The main draw to these weights is the app that pairs them. It’s free to download but does require a $12/month subscription to use the main features of the app, although it comes with a free 30-day subscription. Standard features include but are not limited to tracking your workout and progress, trainer-led classes tailored to your workout goals, changing the weight heaviness from the app, and calories burned. The main draw here are the classes offered. Each class is tailored to what you want out of your workout, such as strengthening vs. skill. The customization capabilities are good, but not great. For the cost of the dumbbells themselves and the subscription, I expected a much better app. I didn’t give these 5 stars for a few reasons that added up for me, some of which include the downsides to the app I mentioned above. First, the weight increments are a bit weird. Starting from 8 lbs., it increases in increments of 6 lbs. which seemed odd to me. Because of this, it jumps from 8 lbs. to 14lbs. to 20lbs. and so on. I do some workouts that require 10 lb. dumbbells, so this was a bit of an inconvenience. Another downside is the fact that it doesn’t come with a wall charger. To save time, I’d recommend getting one with a dual port so you can charge both docks at the same time. The last reason is the app. The subscription seemed steep to me, especially at this price point for the dumbbells and I didn’t use many of the features. The classes were nice but didn’t specify which ones were for the dumbbells vs. other products the app supports. It can also be a bit buggy at times. If you don’t see yourself using the app much, maybe find a cheaper set of dumbbells as this one’s main draw seems to be the app. Overall, I think these dumbbells are worth it if either yourself or your household uses different size weights between 8 and 50 lbs. and you want to save space. Also, the classes could take the place of a gym membership if you prefer working out to a set program. However, if you want smart weights and don’t need the app subscription, I’d recommend looking for a cheaper set of smart dumbbells as the app didn’t impress me enough.

Great products, works well and was easy to install!
