Title: What a waste.
Review: I purchased this product for approximately $17+ for a package of 3. When I received the product 2 of the hot hearts were already completely crystallized, meaning the gel like substance had already hardened. The hot heart should only crystallize when the metal disc is bent which releases the heat. At first I thought that it was due to shipping that the hearts crystallized. However, after boiling them in hot water to reset it back to the gel like state and wait for it to cool to room temperature, I was disappointed to find out that they crystallized again after cooling and therefore they were useless. The one heart that was not damaged only worked after one use and then it was useless like the other two hearts that came in the package. Money I could have used to buy gas for my car.
