Hear! Hear! What he (Carlos) said!!!

There is a thing as trying to be too cheap. Most of these "lower" priced units are made for drinking water. All they have to do is get close. Also, if this RO unit is going to be any where near the saltwater aquarium, beware of salt spray and the corresive effects it has on many metals.

I just purchased one of these units from Tim and I have been extremely pleased with it so far.

Like Carlos so eloquently stated, "You get what you pay for".
