Review on RAINSOFT Reverse Osmosis Membrane - Enhanced Compatibility for Efficient Performance by Jon Manning

Don't waste your time and money! This item is not compatible with RainSoft and the seller is misleading us. He claims they will work, but after trying, they don't work and aren't the right nipple size to activate the system. The water doesn't flow properly. As soon as I discovered this I requested a return or repair of the product and he only accepts returns if the product has not been opened in the original packaging. He is one and should be removed from Revain if Revain truly cares about integrity and their customers!
