Five stars in every aspect
Five stars in every aspect. I called around to many companies selling RO systems and US water systems was by FAR the most knowledgeable and helpful in choosing the right RO system for me. The RO system came with a very detailed instruction manual that made it very easy to install. I selected the wrong color faucet and customer service was helpful in getting my return setup. Highly recommend and hope this system lasts a long time.
