HotSnapZ Reusable Round Hand Warmers

Great for arthritic hands!

Good! They are a little hard to get started the first time.

Warm hands cycling in cold weather

I like the product and it keeps my hands warm while cycling for about 30-35 minutes. The problem I’m finding is that after a few times reheating in boiling water, they harden when I move them, before I’m ready to use them and without snapping the internal device.

Not just a hand warmer

I used it on a plane to relieve pressure on my ear. It helped a lot.
