I run an ink bird with 2 aqueon presets.
BRS preaches about heater failure, why would I spend more than 10 bucks on a heater im just gonna throw out every year?
You have to realise they are a retailer first and their videos are meant to move product.
I use controllers so I do not use the thermostat on the heater except back up. I bet I have not had a heater fail in 10 years. I probably jinxed myself.
