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.

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.

So far working good and I like it.

As advertised

Other than the suction cups , it's working good so far. Only had it a while

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.

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.

Excellent heater. Very accurate maintains water temp in my 125 to within 1/2 a degree. Excellent quality.
