So my wifes community tank had a Ick breakout so I went to get a cheap heater to warm the water up for a few days until we got the Ick under control. I found these Top Fin heaters at Petsmart and figured since it will only be used for a few days I'll get one. It ran for about an hour and when I came back to check on it I found it was completely full of water. luckily it didn't electrocute me or the fish. I even let it sit in the water for about 30 minutes before plugging it in Soon as Petsmart opens I'm returning this POS and getting a Stealth. Lesson learned you get what you pay for.
