O2 Cold Therapy Knee Wrap with Ice Pack and Air Compression Wrap, Fits Like Universal Knee Pads Designed for Cold Compression, Knee Support for Men and Women with Bruised, Strained, or Sprained Knee

The single most effective knee compression I've ever used, plus beautiful cold. Leaky ice bags no more, and the compression really holds it onto your flesh to get the chill in deep.The length of time the cold lasts depends on two factors: how cold you got the gel packs first, and how hot the environment/your flesh is. Some notes:-Using a refrigerator is useless, don't bother-Using a "standard" ice-making side freezer gets them to a very chill temperature that lasts around 20 minutes. They will feel thick but liquid within. This depth of cold is safe to put on my skin; it will chill my knee, but not burn me.-Using a "deep" freezer gets them to a slushy state within. You can feel solid crystals within. This level of freeze is NOT safe to put on my skin; I need a thin rag or pant between my flesh and the gelpack. This level of cold will last for ~20 minutes until it turns into "standard" freezer temperature above, when I remove the protective cloth.If you are in very heated conditions (90F + environment, or your flesh is hot from strong exercise), the cooling power of the gel can be reduced ~25%. Fortunately, the compression sleeve does protect the cold gel from the environment a bit.The product is NOT easy to walk around in. I have done it (at a mall even), but the thickness forces you to walk a bit funny if you have them on both knees as I do. For around the house, it's fine.I worry the air bladders will break someday, but no evidence of any leaks yet. Also, the connection from the removable air pumps to the bladders seems a bit on the delicate side. Three weeks of continuous use, and no obvious malfunction yet.WARNING: They are much, much larger than shown in the image above. When swollen around your knee, they are like a small pillow strapped to your knee wrapping partially around both sides and the entire front. The image on the picture is what they look like WITHOUT the gel packs inserted and with no puffed air compression.

I really like this knee wrap, but it's not quite perfect. Pros: First of all, it is really sturdy. The straps and Velcro appear to be well-made and I believe they will last a long time. The little hose for the pump device screws onto the device and can be put back on if it should ever come off. The ice pack attaches with Velcro to the actual wrap. The fact that it comes off to go into the freezer is a very good thing. The ice pack also seems to be very sturdy. It is also VERY cold! I think it gets colder (by a lot) than any other ice pack I've ever used. I use the device over jeans, and can only tolerate about 10 minutes, since it's so cold. That is actually helpful if you want to use it for both knees without refreezing between uses. The ability to inflate it a little seems to help. For one thing, it really keeps the ice close to your leg. It works best to deflate the device before removing it, since it's hard to deflate without the pressure of the straps. Cons: The ice pack doesn't go all the way around the knee, only the top and sides. There is also no ice directly on top of the knee cap. But I have found a way to overcome those flaws. I use a separate, rectangular ice pack (about 6" X 10") for the back of the knee. I place it under the straps as I put the device onto my knee, starting with the top strap. If I want ice directly on my kneecap, I use a small dental ice pack for that. There is plenty of room for those "extra" ice packs, and with them, I get a really good result. After I get the straps tightened, then I inflate a little. SUMMARY: This is a substantial device that works well as I have described. I would buy it again and would also recommend it. I read a lot of reviews before buying this, and believe this is the best for what I wanted.

Very simple to use, stays on leg, doesn't move around, no water from melting ice, freezes quick and lasts long time. Had one from 2009 and only reason I ordered another is I lost the ice pac. Outer sleeve still looks brand new and still holds the air. Yes I would recommend

As a physical therapist and strength coach, I've purchased lots of different cryotherapy wraps for my clients and patients. I went ahead to give this one a try and my clients/patients and including myself find the fit is quite comfortable.It provides a great snug around the knee joint and along with the pump mechanism, it really wraps the ice pack around the knee well.The only complaint I have is the duration of the ice pack. Like many others mentioned, the ice pack warms up too quickly, I'll say 15 - 20minutes max. Now I don't even use the ice pack that came with this product since its point less to keep it on for such short duration, so I just place my own colder ice pack and then wrap the sleeve over it. Works great.

So I choose to purchase through this company as they promised delivery in two days. My son had just had ACL surgery and needed compression and ice ASAP. Arrived 8 days late. Had I known this, I would not have bought it from them. I wrote a review saying that and they responded by saying please take your bad review down as it looks bad for them and it was Amazon’s fault not theirs. No apologizes at all. They resent this request me again when I didn’t remove my review.The product itself though is what I wanted. The outer brace molded well around my sons leg, The Velcro is strong enough whilst under compression which was good. It’s easy to use, it’s soft and comfortable. The attachable ice pack however isn’t great. Under the compression it leaked the first time of use. Not knowing if the gel leaking was going to be a problem for my son’s open wounds I contacted Amazon for a refund as the company don’t sell the ice packs alone.The company didn’t offer to send another one but instead once again ask for me to pull down my first review. If I did, I could keep the faulty ice brace and they’d talk to their boss about a refund. They informed me that its not their fault, they don’t make them, they are just suppliers with a warehouse in the USA. Firstly, why would I want a defective product, I have a right for a refund and it isn’t determined by me to having to remove a true and valid review before I can get a refund. I’m hoping I do get a refund. I have reported the incident and interaction to Amazon.
