I also bought a Hydor Theo 300W 3 years back. It ran fine for 6 months before it stopped working, the temperature was down to 75 when I got home from work. I called up petsolutions and they sent me a new one. Again it last for about 6 months and this time it almost cook my fishes, I was lucky these were all adults. I found that they were having lots of recalls. I will never buy Hydor again. In the past, I had Ebo Jager quit, but it always just quited and the water will cool down.

I've got 2- 100 watt hydor theo heaters on my 55 gallon discus tank and haven't had a problem. but I haven't had them for very long, I'm also with Eddie I'm a big fan of ebo jager. also get 2 small heaters, and not one big heater.
I big one is just going to cook the fish, having 2 heaters will heat each side of the tank evenly.
"DON'T HOOK FISH,BUT GET HOOKED ON FISH.
15 gallon (using for grow out)bare bottom discus tank,3 young juvies,4 fry.
If the visitherm is holding the temp, just stick with that until you receive your order from Ken. That's 3W/gal, and it should be OK in a normally heated room... tape some bubble wrap on the tank if you need to in the meanwhile...
Ken's top shelf- as good as it gets. I have no regrets doing business with him, none at all...
The best security is to use a temperature controller.
You can use it to control temperature and cooling fans.
Sorry to hear about the heater malfunction. I had the same fear myself, and decided to go out of my way to overt disaster before it could happen, and bought a controller. Now I can rest assured my fish will never get cooked with one of these;

Ditto on Kensfish!!!
I have been replacing my Stealth 250's (had two stick on ) with Jaeger 250's from Kensfish. And am very pleased with them
And as a matter of fact my Finnex HC-810 controller that I ordered from Kensfish three days ago (pretty quick shipping) arrived about 4 hours ago and is now hooked up to two Jaeger 250's in my main tank.
The recent sticking on of two of my stealths has me paranoid about them they were both less than a year old I have had no other trouble from the stealths before till last week.

I just bought a 300w hydor theo 4 months ago. Hearing all this bad press about the hydor makes me want to change it out now.
