Product review (5 stars): Love this product
I read all 14 reviews and went ahead and bought it.  So far, so good!  It is working just as promised.  I think part of what helped me was reading everyone else's responses.  I made sure I had everything tight.  I ran the hot water before I hooked it up.  I knew to take the round thing off the bottom of my faucet so I could attach the nozzle (the nozzle sucks - it throws water and aerates a bit too much), but it has to be there for the dishwasher attachment.  I was also able to attach it without any tools.  Anyway, my daughter helped me hoist it onto the counter and I had it hooked up and running in 10 minutes.  We HATE washing dishes and this is worth the price.  Everything has come out clean and shiny.  I am not afraid to eat off my own plates anymore!

It is a little large for most counters, but it fits under my cabinets and the hoses are long enough that I have it shoved in the corner so I have a bit of counter space next to the sink.  My apartment is small (kitchen is a 6 foot long galley), but I am more than happy to lose the counter space to get clean dishes in return.

Check all hoses before turning on, watch for leaks the first time you run it, and pay attention to plates in case they drop down through the rack and stop the spinner-thing (my salad plates cannot go in the right-back corner - have to be in left-back corner).  Well worth the price so far!
