I have Deautokey interior LEDs in my GTI and ECS ones in my Audi. One or two diodes on the Deautokey dome lights flicker on me every 6 months or so. Deautokey has been great with sending me free replacements along with extra bulbs (I pay nominal shipping) to change them out under their warranty which is great customer service but a little annoying quality wise. It's just the dome lights too. The footwell lights and trunk light have been great. The ECS ones in my Audi haven't had any issues.
