After our water tested high in Uranium, I was all set to purchase a reverse osmosis system but found a link to the Pure Effects web site. After reading the reviews, and checking test results posted on their web site, we purchased the Ultra-UC. The quality of the kit is excellent and the installation was done in under 2 hours thanks to the instructions provided. We also connected our refrigerator ice maker/water dispenser. We have been using the system for about two weeks and so far we are very pleased with the results. I've recommended this system to our neighbors.
