Customer Ratings & Reviews

Its awesome, love the hot and cold features on the attatchment.

It is good; need to be careful when u use it at high speed.

Great to relax muscles with the cold setting. I always use it in the warm aetting before games to loosen up my musclea and be ready to play

Easily the best 100 dollars i have spent! Both hot and cold functions work well.

Perfect for sore muscles after doing my daily 20K walk.

Definitely what I needed! Love the temperature functions!

This was a gift for a family member. She loves it and says that it works so well

It works just not as well as I would like. I wish that all the attachments could produce hot and cold.

does all right seems better build quality than the cheap amazon knock offs that flood the market, battery life is mot the best and it’s annoying that it auto shuts off after like 5 minutes

Not a great product, makes too much noise and doesn’t make much of a difference after the massage

Being an avid runner, I have used message therapy devices in the past. Overall I like these devices and the relief they provide. Until now the devices I have used did not supply hot and cold options. I now see what I am missing by having used the Sharper Image PowerBoost Pro. This device comes with several attachments providing different types of deep tissue messages. I like the fork one as it allows you to direct target a particular muscle or specific area. The real star of this decide is the hot and cold attachment. The ability to apply heat or cold to stiff and sore muscles really changes the game. The hot setting will go to 115 degrees F while the cold attachment gets as cold as 38 degrees F! This range is perfect to treat various muscle groups and discomfort. You also have various speed setting to make the impact lighter or harder. This device is also easy to carry and cane easily be brought on the road as needed. The battery will last for two hits of message on a single charge. Enough for several treatments. Overall I really like this device and would recommend it.

This has barely been used does not function well at all the heating element does not work properly and with only the head shown no other attachments have heat. Super disappointed this was a gift from my husband for Christmas and is now not returnable of course.

Percussion massagers have come a long way from those bulky, corded, single head units of the past. One thing they had was heating, that a most of cordless units didn't, aside from the professional units at high price points. Thankfully, the Sharper Image PowerBoost Pro now gives you both heating and cooling for a price conscious value. This unit is incredibly compact and well made, with a metal pistol handle and rubberized barrel. Operation is simple: the dial on the back allows you to adjust 3 levels of heat and cooling identified by red or blue dots respectively on the rear display. The power button located at the base of the hand grip requires a 2 second press to power on, then pressing it individually allows you to increase the intensity up to 6 levels easily viewable on the rear display. It comes with 4 heads, including the powered head, and a case. Initial charge took a couple of hours, then I started some much-needed kneading on my back after a day's work. I experience tightness on my lower lumbar and knotting just below my shoulder blades. I found it easy to maneuver to the areas on my back with just one hand. On level one, it has more of a thumping motion whereas the higher levels felt more comfortable, settling on level 3 for most of my needs. Having used it almost every day for a week during the stressful holiday season, I feel I can depend on coming home and relieving my aching muscles. The heat works really well and feels like a heated car seat, but the cooling feels drastically colder on its highest setting and is conceivable for post workout relief. The other non-electrified heads like the ball and the flat pad are good for either joints or leg muscles. I haven't quite figured out what to use the fork for as it produces more of a jabbing feeling than anything else. I really like this percussion massager for its features, low price point and long battery life (3 of 4 bars in a week). It feels like a premium product, is easy to use, and provides heating and cooling.

There are a few pieces of equipment I use for workout prep and recovery. One of those is percussive therapy guns. Which gun depends on what I'm looking for. From Hypervolt to Theragun they all have the strongpoints. The PowerBoost Pro is the choice for the foreseeable future. First note is the size. About a 1/3 smaller than my Hypervolt, it is much easier to carry around. The case it comes in creates a nice compact form factor that fits snuggly into my bag and is ready to go whenever I need it. It is weighty, but for me, that adds to its sturdiness. My 3rd party guns can feel cheap in the trim and/or attachments. Not here. Very sturdy. In relation to the size, the punch it packs is substantial. It has 6 levels of pressure, and I normally only need to get to level 4 to get the results I need. Also, the glide is smooth, very smooth. From the lower back to the traps, there is no issue with jerking or uneven pressure. Display is easy to read and navigate. I was up and running in 2 minutes. Battery is excellent. I have been using 1-2 times a day with temperatures at both extremes for a few days now, and have yet to reach 50% battery. The big feature...the hot and cold therapy. The temperature heats up and cools down very quickly. Usually within a minute. Whether using to warm-up the muscles or for recovery, I do feel the 2-in-1 combo is effective. The negative, 1/2 of the star lost, is that is doesn't permeate through clothing very well. Not sure what i was expecting. I wear a lot of compression clothing and tanks, no big issue there, but if I am in a hoodie, the hot/cold is not getting to the skin without extreme user pressure. Anything thicker than a tee would be moot. The other 1/2 of the star is something that may be a defect. After so many minutes, the gun simply cuts off. It will turn back on and begin again with no issue, but it can be jarring. In the manual, it "enjoy your massage for up to 10 minutes," but it doesn't specify it has a auto shut-off. If that is the reason, there needs to be way to turn that off. At this moment, I'm attributing that to a defect. Knowing those two parameters, I still would recommend this without hesitation and will be buying one for my mom in the future. In the gym bag it stays, ready for work! Get moving!

I have had many massagers in my years to help with post cycling and running workouts, most of them corded. I am simply amazed at the power that this cordless massager can produce. I have had the opportunity to use this now every day for a week and I cannot even use it on its most powerful setting. I hover around setting 3 - 4 (6 is the max). The Heat and cold function work very very well and while I prefer heat, the unit can get sufficiently cold when needed. There are three different heat and 3 different cold settings to choose from. I have had the opportunity to try all the attachments but I prefer the one that was attached when unboxed which is the hot/cold "ball". Charging this unit is simple with the now industry standard USB-C and takes approximately 90 minutes to charge fully. I found that I had to charge it after day 4 of use while using the unit approximately 30 minutes with each use. Thank you Sharper Image for not having your own proprietary charging port!! The unit gets aa bit heavy after 20-30 minutes of use as this is a very solid and well built product. I highly recommend this product as it functions as advertised. I do not think one can be disappointed in this offering.

Had to return it. Battery didn't last long at all. And the intensity was not great.

Wored well at first, stopped working by two weeks. No heat or cold. I returned it. Received my refund within two days. Thank you

The temp adjustment dial stopped working. A few times it felt like the gears were popping during temp adjustment. Now temp adjustment doesn’t work at all. Going to return.

This cordless hand-held massager is game-changer! Its portability and lite weight makes it my go-to for quick relief on the move. The adjustable speed settings and various attachments catered to your specific needs, offering a customizable massage experience. The ergonomic design made it comfortable to hold, and the rechargeable battery lasted longer than expected, ensuring uninterrupted sessions. The compact design makes it easy to use anywhere, and the adjustable intensity levels cater to various preferences. It's like having a personal masseuse in the palm of your hand. Plus, the interchangeable attachments provide diverse massage experiences, targeting specific areas with precision. Our favorite attachment is the hot/cold one. You can pick from various different settings of either warm or cold. I was shocked at just how fast this unit gets cold. And it comes with a nice carrying case that’s is nice to travel with or for storage. Overall, a fantastic tool for targeted muscle relief without the hassle of cords

I like that the unit came with the temperature head installed on it, because that is all that we have used. The battery takes about 3 hours or so to charge from near empty and lasts a good long time. It does have an auto shut off after running for awhile. Its easy to hold the button on bottom of handle to turn it on (display comes on). Then select hot or cold or neither with the dial around the display. It takes 30 seconds or so to get hot or cold. Then quick press the handle button to turn it on and select the power setting. No one has wanted to use it above a 1 (lowest) setting. It has plenty of punch at the 1 setting and the heat feels really good on sore or tight muscles. I like the cold setting for working out those morning after aches and pains coming from a warm bed. The compact size is very nice, makes it easy to pack and take with you, even in its carrying case, which holds everything, except for the USB charging block you need for charging, which it does NOT come with, you have to provide that. It charged with all of the five different ones I had on hand to test it with.
