Quality product
High quality product. Easy to install. I have been using this RO for 3 months now. It works well, water taste is very good. Customer service is also very good, friendly and helpful. Only thing I didn’t understand when I purchased— when you choose free shipping, they do not process your order for 7 days +. Then they ship the order, it took 2 days for the shipper to get to me. So if you want it quickly, you need to pay them to process it in a timely manner.
