Been running a 8 switch unit for over a year...no issues. Works great.
I've got the 8 switch version. Easy to hook up and use. I've had no quality issues, but I do wish it had a memory for your last settings (which lights were on) after shutting off/restarting the vehicle. Other than that, I feel it's a great value for the money.
That said; can you tell me how you wired up the small red wire?
I haven't been able to see locate a 12v acc in the fuse box that would work.
