I had that specific one overheat and it cracked the glass and started leaking in the tank. Stay away from glass in my experience anyway. I got a full refund and ended up getting a hydor inline heater and could not be happier. Less equipment in tank. Win win. But seriously stay away from that one.
Wanted to add the hydor inline 300w is on sale and even cheaper than the 200 and 150w. Now would be time to get. $10 less than when I got it. Killer deal
