Review on 🐠 ZMS Submersible Aquarium Heater: Intelligent LED Display, Quartz Shell Safety, Dual Temperature Control by Hunter Wyn

I have no idea where it is now but it must have been short lived or I would still be using it. I had bad luck with heaters. I am lucky that I have been using them for over 3 months. They get dirty and difficult to clean, or there are no instructions and I have to read everything in Celsius. Some you install outside of the heater, but the length of the cord is so short that it's impossible to change the temperature and at the same time look at the heater to see what you've changed it to. Most just stop working and you come and check on your fish freezing in the cold water - this annoys me a lot. We must insist that these companies produce more reliable products.
