Heat click.. for but for long.
on 16 March 2016
These cute little pads do the job they are supposed to.
At this price you would be silly not to purchase them.
However, unfortunately, after only about 5 uses, the liquid eventually fails to work. It solidifies and you have to boil the heat packs in boilding water (with a tea towel on the bottom of the pot so it doesnt burn the plastic) until the substance liquifies again.
