"I would call that a win."

It took me a few days slowly turning the dial up to finally get it where I wanted. I have it set to 81F to get a 77F water temp. Checked the accuracy of the heater with an infrared thermometer. You program it for temperature you want your tank to be. Temperature is slightly off by running a little warmer. The heater is easy; turn the dial to set temp and plug in. The suction cups are large, high quality and seem to stick great.

"What a long."

It just cycles through to 93f and starts over. Bought it as a chiller for the k40 CO2 laser. I had a thermometer on opposite side of tank and the heater was dead on true. This has the best controller that I have found on the market. The cover over the heating tubes is great, the turtles claws can't damage the tube. It does blend well in some setups and may look bulky in others. After several weeks of running the heater.

"I bought the 7."

I got the 200W variant for my 54 gallon corner tank that's housing goldfish. When i installed them, i let them sit in the tanks without power for 6-24 hours. This little heater is perfect; this is our third purchase of the same heater. So far I like it setup was super easy. They promptly fixed the issue without any delays or drama. I hope these suction cups work very well. The heater is easy; turn the dial to set temp and plug in.

"I bought the 7."

The red light means it's off, blue light means the temperature is constant. --The cylinder or rod diameter is bigger. I think it works well to not stand out like other heaters. This heater is NOT fully submersible. This this is amazing and is worth the money. Sometimes you may have to tinker around with the dial. For Discus you need warm and accurate heater and this seems to do the trick.

"Highly recommended."

So when I first received it it didn't work and I was very disappointed. The temperature gauge is fairly accurate in my 55 gallon tank. I will definitely be buying another one for my other tanks at bigger one. I have it set to 81F to get a 77F water temp. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. The heater is being used in a 40 gallon breeder. The bonus digital thermometer it came with has been super helpful, and is accurate.
