"Until the next time."

I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I think it works well to not stand out like other heaters. Checked the accuracy of the heater with an infrared thermometer. You don't have to worry about wide temperature swings with this unit. I noticed my old hygger heater beginning to fail and my wife ordered this one. The heater is super thin and the reflective surface is interesting. Two inches above that is a waterline for maximum.

"No issues."

It took me a few days slowly turning the dial up to finally get it where I wanted. The bonus digital thermometer it came with has been super helpful, and is accurate. The line is there due to regulations in certain countries. I have it set to 81F to get a 77F water temp. The cover over the heating tubes is great, the turtles claws can't damage the tube. The temperatures are pretty accurate. I dont know, and havent tried just yet.

"Seems very well built."

This heater is NOT fully submersible. It took me a few days slowly turning the dial up to finally get it where I wanted. Keeps the water consistent and it's easy to adjust! And kids love pushing all sorts of buttons. Will update my review if any changes occur. No biggie, but annoying nonetheless.

The heater is easy; turn the dial to set temp and plug in. We wish the controls were available in Farenheit also to make things a little easier. I was worried about the quality but I am thoroughly impressed with this heater! I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. When i installed them, i let them sit in the tanks without power for 6-24 hours. This is a great heater that is very easy to set up and program. Would be great to be able to tune that to.
