I can speak on this. I installed a Litejet 48 into my new home in 2007-2008. I love the thing. It's very reliable. The power switching is very industrial based. 25amp solid state relays are PWM switched with a max 8 amp load. I've had one go bad, it was my nieghbor helping me wire a ceiling fan. He shorted the output while it was live. He didn't know they can't survive that. I put another one in and it was fine. I've had a couple of stuck switches, but nothing major. The cheaper default switches could be better in my opinion, but I like the fact they glow in the dark, so easy to find. Another small issue was I think I have a stuck input on my basement circuit, it keeps cycling like a stuck switch, but even disconnecting didn't fix it. I was fairly sure a long power cycle would fix it, but just set it to on/off without dimming to fix it short term, and haven't gone back into the controls to set it back to dimmer since then. The rest of the house is flawless.
As far as customer service, flawless. I had a couple of bad motherboards in my system as a result of shipping damage (i think) as they showed up in the dead of winter and sat outside for a day before I got to them. The snow got into the box is my thought based on the discoloration of the board. Anyway, I had a senior tech at Centralite on the phone for a couple of troubleshooting sessions and he was very knowledgable and courteous. I was shipped replacements at their cost and fast. Back up in a day. I can't really see it going any better honestly.
I have a little background in EE / Industrial PLC stuff. The design is SOLID. I really like how they do things. I would do the same again in a heartbeat.
