My rodi system arrived on Monday. I purchased the aquarium model from Aquasafe Canada.

My only gripe about it so far is that one of the DI canisters is a bit leaky. No matter how much I tighten the end cap it still leaks. I'm sure some plummers' tape will take care of that. Oh, and it took me two hours to put it together.
With how much water I'm making, it will pay for itself in six weeks. I need to get a TDS meter, but I'm pleased with the test results. I'm saving the waste water for the washing machine.
