I could not figure out what I was doing incorrectly and thought my freezer temperature was not proper for this flexible fabric wrap; but, after much research (I tried contacting Dr. Cool and the company it is Sold By on Amazon for instructions or advise to no avail) I found out that it's not stated on the Amazon information details nor on the Dr. Cool's website details that the minimum freezer time of 20 minutes ONLY applies if this product is folded, not rolled.This is an important distinction because if placed in the freezer rolled it takes 45 minutes to freeze, more than twice the 20 minutes advertised. If you followed the instructions on Dr. Cool's website details for this product: "Roll the wrap back up and place in freezer for at least 20 minutes." and took it out at the 20 minute mark you would get a product that is not yet flash frozen, that quickly thaws, and begins to drip. I found the missing folded versus rolled information in the "How-To Prepare Your Dr. Cool Recovery-On-The-Go Wrap Video" created by Dr. Cool.In addition I hung my Dr. Cool Ice therapy wrap to dry and it stayed wet for over 12 hours which was not in the least bit ideal when wanting to just use it as a compression wrap as I did not want to get my clothes damp.************UPDATE**************After my third attempt I was able to get ahold of Dr. Cool not by email but by Facebook, they appreciated knowing that their email system was bouncing back my emails and that they would look into updating the "roll" versus "fold" instructions. They also advised me to only wet the back of my wrap till it darkens and to lit any remaining water drip off to prevent the excess water from dripping when thawed, this will also allow it to dry quicker after use. After researching other wraps it all came back to this one because of the innovative patented fabric Dr. Cool uses that allows me to use this for ice therapy without worrying about busting a gel back and the ease of use and convenience of being able to use it anywhere on my body since I have multiple injuries to my legs. This is my go to wrap now albeit my first impression.After a compound break to my left wrist, I imagined some type of ice wrap might bring relief to the constant pain that no medication had touched. Here it is! I bought one small Dr Cool (3"x 25") and felt my first relief since the nerve block used for surgery. (I swear, I nearly cried.) After one evening of icing my wrist several times, I ordered a second so that I could swap them out out every 20 minutes or so. The combination of cold and compression really helps me. I'm grateful for the respite from pain, and intend to rely on these wraps rather than pills (with their negative side effects).I first thought this was a gel wrap like so many others we have. When I opened the box and unrolled it I saw that it did not have gel in it. I put it in the freezer until I needed it. I have one of my headaches today and I put this wrap around my head; it's been about 10 minutes and it's already unfrozen and now just wet.It would make a better compression wrap than cool wrap, with or without being in the freezer. I have the medium size and it's 50" long and 4" wide. It's stretchy and this size would even go around my back. The Velcro on the end works really well. It even has a hole on one end to hang it.This is a different type of cooling/compression therapy than I'm use to. Personally I prefer something with a gel that stays cold longer, but then again if you have an injury that needs to be compressed with ice this would work (just won't stay cold long). It comes in a bunch of bright colors (I received the green) so you can look good while you're wrapped up. :-) 3 1/2 stars{Sample provided for review}The wrap itself is really good. I bought one because per doctor's orders I should ice 5 times a day and I can't stop working for 20 minutes to ice it.A few tips: 1) it will freeze in 20 minutes, but not if you roll it. I just fold in half and put in the freezer. 2) Do not put it on your bare skin! For me, it was extremely uncomfortable, even left my arm pretty red. I found an old sock and cut off the foot and used it as a sleeve under the wrap. Not only did it save my skin, the wrap actually stays cold longer I noticed. Without the sleeve - 15 minutes max, with the sleeve I got the full 20 minutes I needed. 3) do not underestimate the length! I bought the small for my elbow because I thought the medium was too long. Now I really wish I had bought the longer one. While I am getting the benefit and it is still working for me, the longer one would have allowed me to wrap more of the area now that my pain is spreading to the forearm.Overall, a pretty good product and accomplishes what I need it to.I was originally introduced to this product at a Runner Expo and after purchasing one, I decided that since Amazon was significantly cheaper I needed more in different sizes.I would like to point out that the claim that the wrap will stay FROZEN for hours in the carrying case is NOT TRUE, it does stay cold enough that after my 3 hour race it still felt good.The basic use of getting it wet and wrapping it around feels fantastic and it is so much easier then balancing ice packs. I was able to walk all around Disney with two of these on my ankles, only having to adjust the medium size because it was too much fabric for my sandel. (Hence the Amazon order of more sizes)Good wrap for arms and legs. As a computer programmer I use have hands and arms all day at the keyboard. I'm having issues and using ice takes away the pain for a good while without having to use Tylenol or asprin. It says you can run water over them and then put in the freezer, but once you do that, I found I didn't need to do it again for many uses. After the wrap thaws there is enough moisture left for the next freeze.Only complaint is when wrapping it down the arm you have to fold it a bit so that the next wrap will be tight enough to stay and with it being frozen its so stiff it's hard to get it to mold to the arm one-handed. The fabric looks like it will hold up very well under a lot of use.
