hygger Aquarium Heater, 500W 800W 1000W Submersible Fish Tank Heater with LED Digital Display Over-Temperature Protection and Automatic Power-Off, for Saltwater and Freshwater Tank up to 240 Gallon

So far so good. I like the digital display so I can see the status of it at a quick glance. It seems a little large for my tank, but that's ok. It is very easy to install and set up. The controls are mid-line on the power cord, so you can set the temp or change it with out removing the heater or getting your hands wet. It does a great job of maintaining the temp to within a degree of what is set.

So far working good and I like it.

First dont buy this product! I figured i would give them multiple chances and this thing could have easily burned my house down tonight! This product failed in such a way that it blew my breaker in my house before it could cause such chaos elsewhere killing my fish i have given them multiple chances on different watts of heaters of this model and even other products of theirs i will not do business with their products and i recommend you dont either im lucky i found the problem quickly and my electricity did its job and saved me from a big problem.

Bought as backup to the same model I just had to put in as the previous heater crapped out as they always do after a couple years when you least expect it. Very easy to setup and has a highly visible digital temperature display. Highly recommend. Always keep a backup handy if you value the lives of your fish.

These are great if you can look past the size. The aquarium in the picture os a 75 gallon. Its even hard to hide with wood and plants. There is a ln Eheim heater in there too, which you cant see. But that is glass and can break easily, not this one.

As advertised

Really nice unit. Two large titanium blades gives a lot of surface contact. Rally easy to read screen control to change temp super simple. Customer service very responsive, and look at their warranty on the unit. Overall very happy.

This heater randomly decided to charge the water electrically and decided my fish needed steaming bath water to live in, temps reached 110f killing my fish in the process, broken hearted, money lost, injured, this is the saddest day in my pursuit in the Aquarius hobby. Please save your self save your fish and do not purchase this heater.
