I installed this in a residential setting. The system was fairly easy to setup. The instructions could be clearer, but if you take your time you'll get it figured out fairly quickly. While the filters are installed, they still have the packaging on the. Remove the filters and remove this before starting the system up.
Without having a tank it can take 10 to 20 seconds for the pump to kick on and for filtered water to start coming out. A tank would mean instant water pressure. I couldn't figure out how to connect the tank, but Nick quickly responded with some details on the setup. They do respond very fast to email inquiries. I'll likely raise the 4 stars to 5 stars when I get the parts for the tank install.
As for performance, this is the real deal. Our tap water has a TDS of 174. We have 2 refrigerators with filters but they only lowered the TDS to 120-150. The RCS5T lowered the TDS to 17 immediately after installation. Highly recommended over lesser systems.
