Review on 🐠 Uniclife 100W Aquarium Heater with Thermometer for 20 Gallon Fish Tanks by Tina Waters

I was so happy to get this thermometer it seemed so easy to use. Set and forget! I took my old factory temperature setting, suitable for my freshwater aquarium, and inserted it. I've been struggling to set it at 76-78° for two days now, it's either too hot, once at 79.8°, or too low at 74°. I ended up replacing my old one with this one again. So far with my old temperature correct. Received very quickly and was satisfied with the service, the heating is not very good. Just make sure you have a backup before relying on it entirely. Mine might just be defective, but better safe than sorry.
