I bought one used previously and it worked well so I bought a new one for this tank. Heck I even submerged the controller accidentally in water and it's rock-solid.

Submerged? Cool, glad it didn't fry on you... I would only suggest to take a tooth brush once in a blue moon and lightly clean the sensor... Once the Tunze didn't kick in, and water ran low, but keeping the sensor clean fixed that. And using a toothbrush means you don't have to remove it to clean it.
