I have them. Bought them when they first came out, so that's 3 years (roughly). My only complaint with the sequential version - the sequence seems to be a little long for the timing of my blinkers. About every 3rd or 4th flash, the timing is off and the sequential part doesn't finish blinking. Otherwise, I love the lights. If I was to do it again, I would get the non-sequential version. I am only using the white and the turn signal.
I tied the white lights into my courtesy lights under the dash. For my turn signals, I used a trailer hitch splice connector and tied into that so I didn't have to cut into my factory wiring. Maybe that's the cause for the slight delay in my turn signals?
