The cupholder works as advertised. Esthetically it fits the car really well. My only complaint is that the material is quite flexible and so the drink wobbles around a bit in the cupholder. But as long as it's not an open top, it's not really a concern functionally. For this reason on my 911SC, I ended up not using the riser and just put the cupholder directly on the seat rail to keep it low profile and not too high off the floor. Overall, a really good product. I'd recommend.

I've had this idea for 5 years or so, when I saw your product I was excited.
After install i noticed the screws with plastic heads made for finger tight adjustment wasnt getting tight enough to prevent jiggle/rattle.
When I tighten it more the plastic head just pops off.
I had to insert my own hardware to prevent this.

Nice idea, I use it every day.
The cupholder part itself is a bit flimsy and the double stacker design is not quite right to swing nicely. Nonetheless it’s way way better than no cupholder at all.
