Well shoot. Wish I had known this last week when I received my 50W. First few minutes of reading and watching the vid I was pretty upset.Especially since another heater ( not Coop) went rogue yesterday. I woke up to a very pink dead Amano Shrimp in a tank at 98F. I lucked out and got the heater out and the other shrimp and fish survived. Anyway, as I sit here looking at the heater, I decided to keep it and I feel it will be ok. I really like this little heater.
