BitcoinBeliever: This heater malfunctions quite often. It is NOT reliable to keep the water at a consistent temperature.
On a side note, it looks great.

justin: This is by far the best fish tank heater I’ve ever purchased. I have a red eared slider and he’s very destructive this thing is unbreakable and the suction cups on this thing are next level I’ve had 5 other Hester that after about a day to a week he rips them off the wall and it’s floating around after about 2 months he still has even made it move a inch 10/10 turtle heater. It’s also supper easy to program to the heat you want it to unlike a lot of heater we’re you have a little dial and it’s allways 5 degrees of so you have to guess and finagle with it for a week or so this guy is all digital and is super simple to use

James KitleyJames Kitley: I have bought multiple heaters from Vivosun over the last year. I think the heater looks modern and sleek and is very easy to use. I really like how it has a digital display/ setting instead of a traditional dial type heater adjustment and its not glass. However, I find they lack in quality control of the product. I have a tropical aquarium I set at 79F. It was keeping the temperature PERFECT, it was very accurate. Then after a few weeks it went wonky and was inconsistent in temp control, and had to buy a replacement. I also have a goldfish aquarium that I keep the temp at 68F and that heater has always worked amazing for that temp setting without breaking. I would also like to mention I buy the heaters for a wattage higher than needed as to not overwork the heater from running 24/7. That being said, I am disappointed that I have had to replace multiple heaters over the last year for my tropical tank because they don't last that long. One of the heaters I bought did not work right out of the box. I could not adjust the temp, it was broken. I reached out to the company and they made it right and sent me a new one. I also want to mention that I have never had an error code like...
