Product review (1 stars): Good product, lousy service
This system works very well. We live in a very hard water area and my dishwasher was atrocioiusly gunked up with calcium deposits. I cleaned it all very carefully by hand using food grade acetic acid and it looked like new. Then I installed this filtration system and it worked like magic: the dishes are sparkling and the dishwaher stays nice and clean. So why only one stars Well, when you go to buy replacement filters (and I'm talking about buying them directly for Difi) it all gets sort of touch-and-go. If the company happens to have them in stock, all well and good. But my experience is they tend not to have them in stock. Even so, they are happy to take your money, keep you waiting for weeks and never communicate. On my last order, after 2 months, numerous emails from me to them and no answers,  I tried calling and the message box said: "the message box is full, please hang up." At that point I was so fed up that I called my credit card company and had the charge reversed. Interestingly, that did finally elicit a response from them saying the order had been cancelled. No apology. No explanation. This is a company I won't be doing business with anymore.
