Bests & Worsts Reviews from Amazon

This is our 2nd Bonavita BV1800 in 4 years. They both suddenly stopped working one day around the 2 year mark. We took great care of them both descaling and de-oiling them with the recommended products. Our 2nd one failed yesterday so I decided to disassemble it this morning thinking I could maybe clean it or blow out and buildup. Was shocked to find galvanic corrosion all over the aluminum coil. This is caused by a chemical reaction between the aluminum coil and non aluminum metal in direct contact with it. This includes the steel pump and mount screws that thread into the aluminum on either end, and the heating element. This is prevented on aluminum body cars by using hardware with a special coating. On aluminum boats they use hardware and/or a sacrificial anode. Doesn't matter how much or little you use it, once a certain amount of time has passed, letting the chemical process reaches a certain point, the electronics will fail and the pump and heater will no longer work. Won't be buying another one based one what I saw today, we'll try a Technivorm instead.
