Review on Encompass All Advanced 100W Digital Aquarium Heater - Thermometer & Wireless Controller | Product Certification Included by Lauren Brown

I've read that people were outraged by the E1's bugs. I was like that the first night, day. I checked and that just means the entire heater isn't submerged in water. I added water to cover it. The problem went away so I just put it in my tank. E2 - The temperature has exceeded 94F or 34C. and the heater stops heating. E6. The temperature has exceeded 96F or 36C, the heater stops working. I don't know if you give it time and let it rest when you can use it again, but I'll try that if that's the case. THIS IS A GOOD HEATER, just follow the instructions.
