Great relief for my knee...
I purchased this because I recently injured my knee and am now experiencing arthritis. Upon opening the package, I checked it for leaks and defects. There were none, construction was good. The fit was nice and adjustable too so it was pretty comfortable. My only initial disappointment was that no instructions or guides came with it. Was just a wrapped product in a box.<br />The first test was done with freezing. Everything was great. The gel stayed consistent and didn't harden. It did stay cold for a very long time. Be sure to wear it above clothes due to extreme temperatures and condensation.<br />It performed to my expectations.<br />Second, it is advertised as a hot pack as well. The problem is that there are no instructions not a temperature guide on the product like most hot packs have. Having experience with hot packs, I had to use the info provided on Amazon description along with my sense of how to microwave hot packs. I put it for 30 secs at a time. I noticed that the area hearing was inconsistent due to the gel squeezing from one section to another. I took it out, let it cool and then laid it flat to evenly distribute the gel. Tried again and this worked for better distribution of heating. Again , you must apply this over thicker clothing or you will burn yourself. It was very soothing radiant heat and held up fine to the test. Keep in mind though, if you are in the middle of hot/ cold therapy you need to be able to switch quickly. You'll have to have two devices, whether it's two of these or another device. Switching this over will not happen instantaneously as needed obviously.<br />I was able to receive this product at a steeply reduced price in exchange for my honest and unbiased review. The reason that I'm unable to give this 5 star is because there were no instructions included, which could be harmful to those who don't take time and caution using the hot pack. Also, I think they can improve the pack design to prevent cold spots with a proper quilting design. That would have kept the gel evenly distributed. Otherwise, the product has held up well and performed as advertised. My knee appreciates it.<br /><br />Update: the item instructions were emailed out shortly after purchase, however was caught in my spam filter. Instructions are provided but not with the product.
