"There was only~0."

It's only been set up for a month we'll see how well it does in a few months. After several weeks of running the heater. Just be careful and keep an eye on your temp settings when you have kids over!

VIBIRIT Final Thoughts

"Works just as advertised!"

The temperatures are pretty accurate. I noticed my old hygger heater beginning to fail and my wife ordered this one. I left seller feedback yesterday but have yet to hear from the seller. I will definitely be buying another one for my other tanks at bigger one. But my guys don't read them and don't listen! The suction cups are large, high quality and seem to stick great. Or better yet, conceal it to the back corner.

"Just bought a second one!"

I hope these suction cups work very well. The temperature has been holding all day, even in a colder room. For Discus you need warm and accurate heater and this seems to do the trick. The bonus digital thermometer it came with has been super helpful, and is accurate. Very easy to install and the adjustable temperature gauge is pretty accurate. The controller is easy to use, very accurate and reliable. I got this heater for my 55 gallon aquarium.

"One word of caution."

The temperature gauge is fairly accurate in my 55 gallon tank. 210 gallon ones and one 90 gallon bow front tank. I got the 200W variant for my 54 gallon corner tank that's housing goldfish.

"I'll try once more."

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.

Hydor T20201 First Impressions

"And I am glad I did."

I think it works well to not stand out like other heaters. Now, both points are clear on the package instructions. Temperature is slightly off by running a little warmer. My heater is fully submerged underwater and works perfectly fine. It's pretty noticeable, but I don't really care. If the blue light is flashing it means the heater is not fully submersible. I contacted the manufacturer and they sent me a new unit in less than a week!

"Overall happy."

The temperatures are pretty accurate. The temperature gauge is fairly accurate in my 55 gallon tank. It took me a few days slowly turning the dial up to finally get it where I wanted. The heater protector was very heavy plastic and slim lined which is great. They promptly fixed the issue without any delays or drama. I adjusted the set temperature a little lower to be more in the range I wanted. Sometimes you may have to tinker around with the dial.

"Long heater."

It comes with a hanging kit and can be secured on the edge of the tank. There is no protection from it banging on the glass tank. This heater works, but the dial it isn't very accurate. This is a powerful heater that holds temperature very well. Bought it as a chiller for the k40 CO2 laser. I'm not a big fan of the big glass tubes. There is a misconception on the internet that the heater isn't fully submersible.

"Love this heater!"

This is only day one though, so I shall keep an eye one it. Seems to keep the temp n the tank fairly regular. I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I have it set to 81F to get a 77F water temp. The heater is easy; turn the dial to set temp and plug in. It does blend well in some setups and may look bulky in others.

"This heater works great."

This does a great job at regulating the temp in my 10 gallon. I adjusted the set temperature a little lower to be more in the range I wanted. --The heater itself is a bit shorter if your tank is a short one. No biggie, but annoying nonetheless. The setting always stayed the same. This is a great heater that is very easy to set up and program. There is no protection from it banging on the glass tank.

"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.

This has been in my fish tank for a few months now and it's been absolutely perfect! Checked the accuracy of the heater with an infrared thermometer. We would consider a replacement and then we would return the defective unit. So far I like it setup was super easy. I adjusted the set temperature a little lower to be more in the range I wanted. Sometimes it gets outside of it's ability to cool but only within a few degrees. It's only been set up for a month we'll see how well it does in a few months.
