Customers are not satisfied with the sturdiness of the appendage warmer. They mention that the heating chemical pellets tend to migrate and clump.

Fire risk??

Fire risk??
Well, these products did a great job warming my feet, when I pulled them out, the cardboard was extremely hot, and looked like it had been burning??? I know it’s not the insoles of my shoes because I wear white socks with them. Super disappointing because they were really helping me cold feet.
