I’ve had two separate Tunze 3155’s for 6-7 years. Both still work great and I’ve never had an issue other than having to replace the pump (I think I only replaced one). It was cheap to replace and I have two spare pumps on hand if I need them. I don’t really have a desire to use anything else since the Tunze’s have been some reliable.

EDIT: I also bought a used Tunze kalk dispenser cheap that works pretty well. It’s a simple gizmo, not like a kalk stirrer, but it works well.
