I recently purchased this treadmill which is a very good deal given the discounted price. We encountered issues with the screws during assembly. It still has one screw that we can't fully put through as it is very tight (I encircled it in the picture).
The treadmill is sturdy and I like that it has built-in fan too. Overall performance is great. Ifit is a pretty cool app that comes with one month free membership. I like the video, the instructor, the music that comes with the video and that everything syncs up with the treadmill. Similar to what others have said, it is up to you if you would like to continue with the membership, but so far I like the app.

Quick hitters:
Pros-quiet machine, easy to operate, no problems running on it
Cons-not fun to assemble (at least the one we got)
This review will be based on 2 things: operation and setup
Operation:
As far as operating the treadmill this item is very nice. It’s quiet and comfortable running. I am 5’10” and I ran on the treadmill at 6.0 with no issues of length or width of the treadmill. I inclined it a little as well to check that out and that works well too. What I like about the treadmill is that it has some quick starts on the panel where you can simply click “6 and it takes you to 6mph.” It does look like there are built in programs as well but haven’t tried them yet. Overall, using the treadmill is easy and we really like that aspect.
Cons:
The delivery team was TOP NOTCH when bringing the product into the house. That’s where the positives ended with set up. My wife and I opened up the box (no issues all parts looked new and nice) and read the directions. They seemed simple enough. We even watched a YouTube video and it looked like it’d take maybe 30-35 minutes. Well, just over 2 hours later we finished setup. The biggest headache was on the 2nd step. The “grommet” did NOT fit in the slot it was supposed to. I spent 30+ minutes trying to file the plastic to fit it in the slot. It was very frustrating. Additionally, the labeling of the parts (screws and bolts in the package) was confusing and really could’ve been improved.
Lastly I don’t like the marketing scheme they use saying your treadmill won’t work unless you activate ifit. That’s completely incorrect and also really not cool. Just hold the ifit blue button on the screen for 15-30 seconds and your treadmill is good to go
Overall,
We like the treadmill and it’s a good add to our cardio equipment in our basement gym. I would recommend the product but maybe have geek squad set it up to avoid the hassle (which is what should’ve happened for us because I’m a total tech member but it didn’t Happen and I needed it set up by Christmas Day)
So-treadmill for walking and jogging (I run 5 k 4 days a week in nicer weather) is great! (5*) setup (3*)

This treadmill is great so far. My wife and I are both about 5’6” tall. I am about 220lbs and she is about 130lbs. The treadmill feels great for both of us. It has a motorized incline up to 10%. The iFit feature was a bit strange, but we easily bypassed it by holding the iFit Sync button for about 20-30 seconds. Putting it together is not hard, but it is best to have two people available, and you will want a good wrench and patience.
If I have to gripe, the mechanism used for lifting the treadmill to a standing/storage position is a hydraulic shaft. It does a great job, but I worry it will wear out. Also, while it locks when it goes up, I do not trust the lock (built into the hydraulic shaft). For this reason, I won’t be leaving it lifted due to small children being in our home.
Only other thing to be aware of is that for heavier people (like me at 220 or more) will want to walk at 2+ mph, as any slower will cause the belt to feel like it is slipping/lagging.

Very nice treadmill for the price! Setup looks a little intimidating at first but it’s not bad. You will need a second person to help hold it up while you put in the last bolt underneath.
Belt is a little tight at first but it does loosen up. I like there is a simple 1-10 set of buttons for incline and for speed to quickly jump to those settings.
The Bluetooth and speakers work fine but I won’t use them at home so not a big deal to me.
Fans on the front offer a nice breeze.
You don’t have to use the IFit program or activate. All of the big banners and scary DO THIS NOW does not matter. The first month is free but it’s $15 after that. I guess that’s up to you if worth it but not needed for me. I just turned it on and started using it.

Assembly review

I gave 4 stars As I have not used it yet except for about 5 mins to test the belt drag.
My review is based mainly on the assembly, Total time was 2hrs and was my first assembly of any treadmill. My 23yr old daughter helped me. I highly recommend the app BILT which is suggested in the manual, hearing instructions with a short video is easier for me than reading and looking at pictures.
For the most part the assembly was pretty straight forward, the only struggle was some of the screw holes were very tight. Those holes came with transport screws in them, that they tell you to disregard. I did however use them to screw in first to open the hole a little so the screws you use go in easier. Overall I was pleased with how it is assembled and I am looking forward to start using it to increase my health. (So is my daughter) ;)

The machine did not lay flat on one back corner. We had the installers come out the next day after the machine looked perfectly well-installed but we noticed it wasn’t after trying to run on it. It was a few millimeters off the floor on one of the back corners. They came to fix it the next day and said the machine was leveled and so it might be an issue with the floor. They put a piece of cardboard underneath it. We were willing to use it as such, but we noticed that the faster you run, the more likely the belt (or motor?) would jump. The problem persisted & so we had to return it. You can see the cardboard in the picture.

This is a good machine to kickstart my home gym. It definitely requires 2-3 people to assemble as the base is very heavy. It is easy to use and functions fairly smooth. It’s a bit squeaky but a little oil may help that. All in all, a good buy.

Needed 3 different replacement parts sent to me from the manufacturer, just to finally be able to complete assembly several weeks after I received it. You’re forced to sign up for the IFIT service free trial period (it won’t turn on unless you do), make sure you have a decent screen on your unit because the IFIT service IS NOT STREAMABLE!! Unless you have Apple TV which has the app available for download (supposedly) you can only watch the training using an IOS or Android phone or tablet. You cannot download the IFIT app to a smart TV or stream it’s content to a larger display from your phone. Useless service if you can’t see it.

Nooooo
We’re sorry the unit you received needed replacement parts but are happy to know we were able to get all parts sent to you for assembly to be completed.
Please know that iFIT membership is not required to use manual mode on this equipment. You can cancel your membership trial at any time and elect for manual mode.
iFIT compatibility is continually being updated and expanded. We’re sorry it seems that some of your devices have been incompatible. They should be made compatible soon as we continue to expand this service.
Your treadmill should have no problems connecting with the iFIT library, and the app should also be accessible on Roku for your Smart TV. For further information, please reach out to us at [email protected]. We would like to improve your experience with us.

Husband attempted to put together only to find the bar for the console was made incorrectly. Console didn’t fit flush to arms. Looks like they knew the main bar wasn’t the right size and tried to weld more to it. Measurements are way off. This is going to be a pain to return as it is majorly heavy and there are a lot of smaller parts.

After waiting several days for my treadmill, it arrived flattened and with traces of use, it is unfortunate that something like this happens, where are the people who supervise this type of thing, it is true that it is lowered but do not exaggerate.

Great treadmill. A lot of people are worried that you can't operate it without the "connected" mode but you can and it's very easy to get around. It works well and has some nice extras like a built in fan and built in speakers. The biggest downside is that this was a pain to put together. Very difficult and frustrating. But now that it's together I'm very happy.

We’re glad you find it easy to use this treadmill. Sorry the assembly was harder than expected.

Ok this treadmill is seriously awesome. I did a lot of research and digging to find one that would fit all our needs. It’s not super loud when running. It doesn’t shake when I’m running. It has a great display and can hold my iPad while I run. There’s spots for drinks. It has a 300lb weight capacity. It can fold up to save space. When lowering it you can actually let go when it’s halfway and it slowly lowers itself. It’s wide enough for us to run without causing problems. It has great speed. I honestly love this treadmill. It was worth every penny. I’ve used it every other day since I got it and have had no issues. You can also bypass the Ifit stuff by holding the Ifit button down for like 20-30 seconds and then it’s good to go. It took a couple hours to put together but it was easy. Instructions are easy to follow.
