How to use Disposable Heat Patches with Belt

1

Open the Bag When ready to use

Open the plastic bag via the slit on the side of the bag.

2

Insert the patches into the belt

Insert the heat patches into the pockets. Make sure the printed "skin side" is against your skin. It allows air to activate the heat patches.

Works great for fast relief

I like these back heat warmers because they are disposable. They provide the relief I need quickly for my lower back aches and pains. They are easy to use and combiner for on the go travel. You can just throw a few in your suitcase and they don’t take up much space. The warmth lasts long enough for what I personally need it for.

Long lasting pain relief heat pads that fit into a comfortable adjustable belt

I have used this product on my lower back and on my right knee. The belts are very lightweight, and the material stretches a bit to accommodate people who are larger in size, like myself.

Joe N

Works well

I put one on after work every night. The belt stayed in place pretty well.Love how when finished using you can cut it open and nourish your plants with it, super awesome!

Francesca

Good Heating Pad. Not so great belt.

These are great heating patches. If I am at home, I have used them for up to 5 hours. The only drawback is that you're supposed to wear these on the outside of clothing.....negating some of the heat therapy. I would much rather wear it next to the skin and use clothes as added insulation for the heat. Unless I misread the directions, as the item photo on Amazon shows someone wearing this next to their skin. Probably not something you want to wear out in public, but it does the intended job.

Best Heat Patches Anywhere!

These are the best patches you can buy. They are very reliable, I haven't had one yet that didn't heat up, unlike another popular brand. They last as long as advertised. I've been using these for years now and will continue to do so as long as my back pain persists!

Amy Williams

I love them. It keeps my muscles loose and from tightening up. Infact I will order more soon.
