The NatraCure Cold/Hot Therapy Wrap is incredibly easy to use, as one can assume it would be. I popped it in the freezer a few hours for the first use and it stayed very cool for over twenty minutes on my foot. After that I switched it to the other foot and it was still somewhat cool for quite some time.It wraps easily with strong velcro and is easily adjustable. The gel is a bit stiff when first coming out of the freezer but a bit pliable after a few minutes of "thawing." It's very cold but overall comfortable on the foot for cold therapy.I primarily intend to use this item for cold therapy and have not tested with heat yet but I assume it will work just as well. It's a great item and if you suffer from plantar fasciitis and arthritis like I do, or any other painful foot condition, I know you will get temporary relief from this to help in conjunction with your other therapies and treatments. It can also be used in other areas of the body such as the wrist, hand, arm, legs, etc.The price is fair and the quality is good. I highly recommend this product to those who need hot or cold therapy. Read more
