Review: Nice Heater - 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.
Review: I like it. - So far working good and I like it.

## Features

You can switch between them by long-pressing the controller's set button for 2-3 seconds
- 【Overheating/Low Temperature/Dry Running Protection】Our aquarium heater has three intelligent protectors: ①Overheating: When the water temperature exceeds 93°F, the heater displays the error code “HH”, and automatically stops heating. ②Dry running: When the heater outs off water, “Auto shut off” will flash and automatically cuts off the power. ③Low temperature : When the temperature is below 59 °F, it will display “LL” and continue heating. Multiple protections to get rid of "boiled fish"!
- 【Digital Led Display & External Temperature Controller】This aquarium heater features a unique smart LED screen that is completely waterproof and clearly displays the current water temp., set temp., current operating power, error codes, and current operating status.

Simply press the set button on the external controller to set the target temperature
- 【Efficient And Explosion Proof】Our aquarium heater is made of explosion-proof quartz glass and the most thermally stable nickel-chromium wire to transfer heat to the surroundings quickly and steadily.

Note: Please unplug the power and let the heater cool for 10-20 minutes before taking it out to clean the fish tank or change the water

### ⭐ Don't buy this product! I once thought an amazing idea now turned almost deadly!
*by S***Z on July 22, 2025*

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.
