Out of Water Protection
Designed with safety and smart temperature sensing in mind, this aquarium mini submersible heater automatically ceases operation when it is not submerged in water, and the controller will flash an “Er” error code to indicate.

Looks good so far.
This is I believe my third heater I purchased. I like these guys I can trust them. I bought a couple others from other places and learn that you have to be really careful who you buy things from that if they go out can’t kill your fish
Great little heaters! Work as needed and keep a really steady temperature! I just replaced 6 more of my old heaters with these and am looking to get more!!
In the past, I have bought another brand of digital tank heater from Amazon. This one is being used in our quarantine tank and is perfect for our needs. It’s inexpensive, accurate, and easy to use
