So here's my review of my single cup holder. Short version, it's great! I really like having my giant water bottle in my car and not rolling around the passenger floor area.
That being said I did have a few issues. First off with the provided tape it would seal the black part and the blue part together in this photo
The problem I could forsee with this is that if I wanted to change my stereo the black part needs to come off, but not the blue part. So I didn't use the bottom most tape strip.
The only real issue I had was a gap. I think I installed it in the right place, with the shifter housing right in the notch. The holder is right up next to the shifter housing but it still hangs a little too far off to the side.

I think this compounded with not using bottom strip of tape along with not having a drill bit long enough for the bottom screw gives a fair amount of play. I'm just going to cut a small strip of wood in the morning as a shim and use a longer drill bit and not worry about. It is really great. Even with the play and only one screw and not all the tape it is secure enough that I don't worry about it spilling.
