It was an amazing price, they were easy to install, ispring had great customer service and they shipped promptly. I don't usually write reviews, but I'm really impressed. I used to have a Kenmore reverse osmosis system and it only had three filters which Sears cost $198 to replace and Revain $94 to replace. I have just replaced all 5 filters on my ispring for the first time and I still have enough filters in the box to last another 2 years! I called iSpring directly to find out how to get the filters and to make sure I got the right filters and Sean told me exactly how to find them at Revain. He was friendly and helpful and I am very impressed with their products. Thanks very much! jessie
