“The top negative review claims it doesn't stay cold enough and even measured the outer surface temperature of the sleeve once it was applied. The average surface temperature of human skin is 91 degree F which means of course if you applied a non sustainable cold pack against it there will be a rapid decrease of temperature over a short period of time. You shouldn't be applying cold therapy for more than 10-15 minutes at a time anyways and I found the sleeve was perfectly cold enough for 10 minutes of cold therapy. What's awesome about this product is as soon as you're done with the cold therapy you can immediately toss it in the microwave for about 35 seconds to apply heat therapy. My suggestion is to follow the instructions because every microwave is different, 10 second increments until you find out what the total amount of time it takes to sufficiently warm up your sleeve. Excellent product overall.”
“I bought this because I was tired of traditional ice packs that do not ice evenly, in my experience this product easily slips on to a knee or an elbow and gives a even cooling around the affected area.”
“This worked great for after my husbands knee replacement surgery. The only improvement I think would be if there was a way to help it hold the cold a little longer. Otherwise, this is a fantastic product and I would highly recommend it.”
