I use proclip in my E90 and E36. I've got a crappy vent mount in the E53 at the moment.

My big frustration with proclip is how long it takes them to release a new phone holder after iPhone redesigns. It looks like they finally pushed out a 13 Pro Max holder.

That said, now that they exist, I'll probably buy one.
