Have owned many of these, but this brand is the best
on September 27, 2018
I have electric heating pads, small rice bags, large specialty heat bags, gel cold-hot pads, etc. and they always fall short. But not these!
The electric pads can't do cold, the rice bags loose heat quickly and generate hot spots (I kept trying to redistribute the rice which seemed to collect at one end). The large heat bags were ok, but usually heated some areas I'd rather stay cool.
I bought other brands of gel packs with fabric covers and liked the even heating but these are still superior in some important ways. With the fabric covers, sometimes the heat doesn't come out fast enough initially but then heats up too much. Then, with less gel inside than these they cooled down quickly. Also, the elastic was so long that it barely fit my 32" waist.
These are designed perfect! The elastic seems like it'd go down to about 24". It overhangs a bit for me, but I imagine that's so it'd adjust for much larger sizes still. The gel is thicker but still thin and seems to hold the heat and cold much better than anything I've used before. The heat seems to last twice as long, but using as a cold pack is outstanding. Having one for each use is a great perk too! I tend to have gut pain and these help. They're comfortable enough that I have no trouble sleeping with them on.
The one thing I thought was going to be a "downside" was the air-mattress style fabric, but it actually allows me to put it outside my shirt and makes it so I can adjust the temperature transfer. If I really want to push every bit of use out of it, I can put it on my skin a while later and it'll last even longer (which is rare).
