They are less expensive than The brand-name patches. Plus , They stay warm longer than Other patches I’ve used. They get quite hot. If you’re older ( like me) with thinner skin, use caution if you are going to sleep with patch . Leaving on too long may cause a skin irritation, I’ve used these patches for several years and that only happened to me one time I highly recommend for back, and hip pain. They also provide Additional body heat In winter

They have a adhesive on the back and stick to your body very well they work great and last a long time

Great price per patch. Only last 8-10 hours tho. Delivered in a plastic bag-was hoping for a box that's easier to store.

I don’t really use these I found the ice packs work better!

I’ve had problems with American made heat pads where they get really hot and burn out quickly. I even sent a box back after speaking to customer service. A few weeks later, I got my original box back and they didn’t even replace the used ones. It hurts to say this, but save your dollars and buy Chinese!

Opened four patches and all four failed.

I started a timer as soon as I opened the package, and stuck it on my back. Took a bit of time to get nice and hot (not too hot or uncomfortable, but decently warm for sure), but once it got going it easily lasted 10 1/2 hours and was still going. If you're considering buying these, buy them.

These stick well, but does not get real hot, just warm.
