I've only heard of the problems with the 200 watt. Most of mine are 25 watt, 50 watt and 100 watt and 1 that i think is 200 watt but can't recall at the moment. I've had them for several years now and never had a problem. I've lost fish due to other brands but in the years I've used Neotherm I've never had any problems. I was actually very surprised to read the unfavorable reviews. My lfs
has sold them since they came out and never mentioned any issues. Most people I encounter out in the non internet world won't shell out that kind of money on a heater. I will because it's worth protecting an investment of less common and more costly fish.
Oh and my heaters are actively heating much of the time as I have most of my tanks in a basement with nothing but cement and block walls and no insulation.
