Review title: Immersion Heater
Product review: This heater worked really well the first three times I used it, but broke the fourth time. I wrote to Ace Hardware and they sent me a free replacement, but that broke the second time I used it. I may have been doing something wrong (possibly you have to let it cool for a certain amount of time before re-using it?), but my overall experience with this product was extremely disappointing. I gave it two stars just because while it WAS working it worked great, and it really did heat the water very quickly.
