Light worked for about 30 minutes. Changed batteries - no luck, no love.
Edit: Supplier reached out (which I appreciated) and sent a replacement that works as expected. I use the device primarily for game guides that tend to use smaller print. It's perfect and my Skyrim re-mastered play has improved due to being able to read my game guide :) Happy.
Mainly use it for cold. Store it in the freezer and use it when needed. The Velcro is nice for holding in place on your back. Its a ice packet that you can strap on. Other then the strap, its your normal ice pack. I have not used the heat part of it, but I really like how they write the instructions directly onto the ice pack. No need to keep the directions (paper) because its always with the product.
Very handy. Love the magnification and the led light.
Let me say that I bought this for contingencies so I have not actually used it. That being said the concept is excellent as it has a stretchable band that can be wrapped around the body to hold the gel ice pack in place. Instructions also state that the pack can be used for heat as well as ice by heating the pack in the microwave. Should I have to use it and find it wanting, I shall edit this review.
I haven't tried the cold function of this pack but it's a great heat pack. It holds the heat for a long time, more than half an hour. I like that it doesn't have a cloth cover like other packs I've had because the velcro tears up the fabric on those. This one stays nice and neat looking and is easy to wipe clean. Good job!
I had an occasion in needing to use this as an ice pack following a knee injury just before Christmas, and was so glad i had it available. The straps were helpful in keeping it in place. I also had an occasion to use it on my lower back, again the straps keeping it in place, making it possible to be up and ambulated without it falling off. I haven't tried it as a heat wrap yet but believe it will perform just as well.
Great and quite handy with the interior light part of the unit.
Much better than leaky ice-filled zip lock bags! I have used both heat and cold on lower back and my knee. Easy to use and convenient. I keep in the freezer when not in use because thaws and heats up faster than freezes.
Heats up quickly in a microwave. Velcro straps fit my 38" waist. Very satisfied.
It's great. I use this several times per day, on busy days, for all sorts of things, like the tiny print on microchips, and reading details on food labels. As others have noted, it is actually about 2x magnification. So are all the competing products (which appear to be OEM brandings of items from the same factory). 2x is plenty for most purposes. This lens is large and quite substantial. They're not kidding when they call it a paperweight magnifier. The case is a nice touch, and easy to open, so I keep it in there to prevent damage.
