Very easy to install and the adjustable temperature gauge is pretty accurate. Maintains it well except when the weather is already warm then it over heats it. This has been in my fish tank for a few months now and it's been absolutely perfect! Just be careful and keep an eye on your temp settings when you have kids over!

The temperature gauge is fairly accurate in my 55 gallon tank. Beware, but we are hoping for a good outcome! At this time I highly recommend this product.

It took me only two tries to get it to the correct temperature.

"Just bought a second one!"

I went ahead and went with the the larger 300W for my 45 gallon. I noticed my old hygger heater beginning to fail and my wife ordered this one. I use a 50 for a 5 gal and a 10 gal tank. I think it works well to not stand out like other heaters. Checked the accuracy of the heater with an infrared thermometer. Sometimes you may have to tinker around with the dial. I used to try those other cheap heaters sold on amazon.

"What a long."

They promptly fixed the issue without any delays or drama. This has the best controller that I have found on the market. Once attached to the tank wall I've had no issues with it coming off.

"So far so good!"

There is no protection from it banging on the glass tank. This has the best controller that I have found on the market. I wouldn't buy any other heater, unless one of these stops working. It's pretty noticeable, but I don't really care. The controller is easy to use, very accurate and reliable. My marina heater takes a few hours. I like the fact that it comes with a digital thermometer.
