Dangerous grill

My thane grill leaked after two uses. My propane tank would have frost like residue on the tank. I could hear a small hissing. I changed propane tanks, hoping this would solve the problem. I lit the grill and flames came shooting out of the bottom. God must have been watching out for my dad because he grabbed the grill, unscrewed the tank as fast as possible with his hand surrounded in flames trying to get the tank out before the whole grill blew. He did get the tank out but the rest of the grill burned up to a smoldering, smelly mess. Very dangerous, unstable, poorly made as seems to be a lot of Thane products. Clogged easy at first use, hard to clean. Very poor grill.
