Heating Pad

First off, compared to other heat packs with similar liquid-to-solid/boil-to-reset design, this dual chamber is by far, one of the best. I've activated one chamber leaving the other at room temperature, and it gives off the same degree of heat, while letting my skin breath. (The non-activated chamber acts as insulation and as a vent. It was never 'too' hot, but didn't forfeit temperature in the meantime.Also, the mint is invigorating and affected my muscles directly with contact.

The product does it's job! A quick snap and it heats up quickly; holds it's heat for a solid 30-40minutes; returns to normal state with a boil and works again and again. I WISH I had known that it smelled (more like REEKS) of mint. I'm hoping the smell weakens, it is REALLY quite strong - my eyes water from the strength of the smell. Maybe the description says this, but I had no idea until it arrived. Kind of a bummer... But heat pad is pretty awesome.

The size of this was pleasantly surprising compared to other items on the market. Great price, great product.

Works great. Boils to liquid easily.

they work great and they are the perfect size for all my needs

Now that's hot
