- For best results, place your Hyperice X directly on bare skin. You may wear thin, athletic wear if preferred. Place the Hyperice X over knee and align the kneecap ring with your kneecap. Adjust straps until snug and start your session through the Hyperice App.
- Too big or too small - If the device is too big, use included minimizers by attaching the minimizers to the existing straps and secure. If the device is too small, use the included extenders and attach the extenders in the open loops and secure properly.
- Using the device on the maximum heat or cold setting requires more power and may possibly shorten the battery life during your usage treatment. Please note that you can use your Hyperice X while it's plugged in to the charging power cord.

I wanted to hate this because it's a bit pricey but it's amazing! I'm 6 weeks post surgery on my knee and I use this at least twice a day for swelling. It's amazing and works great! It's 100% worth the money and extremely easy to use! It helps with swelling, range of motion and pain.

I bought this as part of my recovery from ACL reconstruction, LCL repair and a partial meniscectomy. So lots of work done on my knee and lots of inflammation to deal with. I started using this about 1.5weeks after my surgery. Before that I was using a full wrap ice machine. I also have full wrap ice packs in the freezer. So I feel I have a good idea on what the different options are. If I'm at home my preference is to use the hyperice X or an ice pack from the freezer. Hyperice is loud when cooling, but it's always ready to go as long as I keep it charged. It can do 3x20min ice cycles at max cold temp. Which is more than enough for me. I usually charge it after 2. Now I still do use my normal ice packs because sometimes it's more convenient depending on where I'm at. However for traveling anywhere, the only option is the hyperice x or similar machine. Now what I do not use anymore is my full ice machine. It is cooler on wheels with a timer and you have to drain and clean it periodically, and it just isn't convenient. I'm not really sure what's up with everybody's complaints on temperature, the hyperice x gets just as cold as either my ice packs or the ice machine. Now the caveat there is I cannot cover the hyperice, it needs good ventilation. So if I'm using it under my desk I need to have 4-5" of clearance or else it doesn't get as cold and you can feel the air from the fans getting warming. However, uncovered it's just noisy. Similar to a small dust buster vacuum. This is for cold only, heat is dead quiet. One thing I haven't tried out too much so far is the contrast therapy, because I'm still not 6weeks out from my surgery. I have fired it up once or twice though. It feels very nice and is an option that nothing other than similar machines can touch. The battery does drop fast with contrast though. You can usually do one 30min contrast session and part of another if you said cold and hot temps that are near the min/max available. Once again not really a problem for me as I'm fine charging between sessions or even using it while plugged in. So biggest down side to the machine is the custom charging adapter. I really wish it was USB C, but instead its a custom 9V/6A block. Battery life could be better, but it would weigh more and cooling and heating takes a lot of power. So I think they made the right trade off (on the battery at least). Another downside was lack of case, but I picked up a shoe bag using in luggage and it fit the hyperice and charger just fine. This is absolutely a luxury item at its current price, but it's worth it for my recovery. I plan on taking it to work and using it in the middle of the day to keep up with knee swelling. Also I plan on taking it on long road trips. It can keep my knee happy and I can charge it via inverter or power bank with ac out. Currently I'm using it while working from home, I can just quickly grab it anytime w/o having to crutch myself to the freezer and back.

Getting a snug fit is a little challenging since I'm right at the limits of the straps and using the extensions is a little much, but overall it works great.

The Hyperice X Knee is awesome! I totally love it. I used to have to put an ice pack on my knee after running, and then a heating pad. They worked, but not nearly as well as the Hyperice X Knee. The app is great too and really makes using the device easy. The batter is fine....I can get a whole hour of therapy without a recharge. If you need more battery time than that, you probably need to get your knee replaced. Not me....I'm doing 2-3 10Ks a week running with no issues, thanks to the Hyperice X knee!

I used it three times. After that, no matter how many hours I charged it, it would begin to work and 2 minutes later it would shut off and there would be a window saying my battery was too low, I charged it for hours, Same thing, I charged it all night long. Same thing. I connected with customer support and asked for their help. I was sent a trouble shooting PDF that I was supposed to try. I did try what they suggested but still the window said the battery was too low to continue. Then I realized--wait---they actually had a PDF of trouble shooting tips all ready to send to me when I first told them their product didn't work? So that means, if they have a PDF of trouble shooting tips all prepared, ---they must KNOW their product is unreliable and they're depending on the customer to make their product work. It's not my job to try and make their product work. My job is to buy the product and use it. Not to take my busy time and go through a trouble shooting list to make work what should already work. Frank Oznowicz I STILL have not heard back from them.

The battery life is disappointing, you pretty much need to charge it after every use and it takes hours to charge.
