Add me to the list of people who was a happy owner until I burned it up as well. I would not hesitate to buy another if I have a need. I actually did some pretty heavy discharge testing with mine, but kept in on ice to help with the cooling. I burned mine up when i forgot about the max voltage level and exposed it to too high of voltage. damon
