Koo-CareExtra Large Reusable Flexible Gel Ice Pack for Hot Cold Therapy - Great for Shoulder, Back, Hip, Knee, Ankle, Foot - Pain Relief for Sports Injuries, Swelling - (XL, 11" x 14") Pack of 2

Pros:* Price - 2 for the price of 1 in most retail outlets. In fact, I've paid double just for 1.* Works a charm, stays super cold for a long, long time, longer than most ice packs I've used.* Large size means I don't need 4 to place on varying aching places. They also flatten down nicely so you can lie on them, if necessary.Cons:* The 2 ice packs don't come with covers, so you do need to use either a light tea towel or buy/make covers. Also, they're super cold, so you cannot use these over a thin shirt... you need that extra layer of skin protection a cover or thin towel provides.Good to know:* Disclaimer: Although dual purpose, I don't use these as heating pads. I use electric heating pads & need ice more than heat, so can't comment on durability if used for heating-cooling over & over. Given that they hold cold so well, I'd imagine they do the same with heat.* Great customer service. Just as I received the packs in the mail, I received instructions in email from the seller to ensure I knew how to use them. I'm an old pro with ice packs, unfortunately, but I do appreciate the care.Great purchase, although I'm a bit annoyed that I'll have to make my own covers for the packs... the cost to purchase is more than the packs, in most cases.4.5* out of 5.-.5* just as they come with no covers.

I purchased this product to help reduce swelling in my shoulder after surgery. I have also used it for pain in my knee and arches of my feet. Very pliable and user friendly. Does not take up much space in freezer as it lies flat.

This is they perfect size to fit and reach both of my lumbar and cervical back pain.

Great to use but doesn’t stay frozen past 20 min

I ordered one and realized I needed more to switch off.
