So far so good. Install last month was easy. Supplied power cord was very short (~3') but that was easy to replace. Cords for sensors and cell were quite long to allow flexibility. Hard to access bonding lug without removing cover which seems like a design oversight. Built in bypass valve seemed like a good idea but spring seems tight so it's mainly a gimmick for most people. At 50 gpm (max flow for my 1.65 hp pump), it's just lifted off the seat. I think it should be getting close to fully open at that point (imo, should start to open around 20-25 gpm). Now that it's glued in place, there is no easy way to put in a lighter spring. System works well at advertised minimum flow rate of 15 gpm. At ~12 gpm, the flow sensor shuts off the cell. Had to bump up speed of pump by 100 rpm over last cell (zodiac). Overall happy with the purchase. Cheaper than the other options and it works. Old system needed at least a new cell which would have cost almost as much as this system and may not have solved all the issues.

Bought this in May 2022 after our old Zodiac SWG failed. Originally was having some issues with the new unit but the rep from the manufacturer was amazing, he went way above and beyond to try and diagnose the problem. Not entirely sure what the problem was in the end but they sent a new cell and it worked fine and then the original was working fine too. Might have just been as simple as an improper connection in the wire that connects to the cell. Anyways, it looks like this was through no fault of the manufacturer but they never pointed fingers at me or the installer and just offered amazing service to get the unit working. It has now been 1.5 years and this SWG is so much more advanced than our old zodiac. Very happy with the quality, service and support for the Digital Nano.
