The initial 'A' models had some issues & I had to have mine replaced last fall because the processor seemed to lose its mind.

Behmor's Customer Service was absolutely wonderful (just like Axiom's) & after I had done some troubleshooting with them online, they sent me a brand new 'B' model with shipping included from the US. It has been flawless.

Hard water areas might be problematic though unless cleaning is done regularly...
