This review is from: iSpring RCC7 High Capacity Under Sink 5-Stage Reverse Osmosis Drinking Water Filtration System
System was easy to install following directions and fits under our small sink area perfectly. We've had it for several months now and there have been no leaks or issues with any of the components and the water still tastes excellent! Video shows our under-sink cabinet with the system installed."

"5.0 of 5 stars A great system upgradeNovember 21, 2017
Verified Purchase
I needed a new RO system. My old system was over 7 years old, it was time for something better. I found the ispring had a 6stage RO system. I also looked at the cost & availability of replacement filters. I like the fact there are filter kits to buy, and are reasonably priced. ... The water from the new system has a nice taste. Overall, the system was well laced,easy to install & works great. I would buy this system again."
