I used this to custom mount my phone on my Harley Davidson Road Glide and it works perfect!! Although I had to drill and tap a second hole, woulda been nice to have that from the factory...
I highly recommend the holder with the Twist Lock Grip (spring plus screw). I have used it on my mountain bike and on a 1,000 mile motorcycle trip.
I want to order 2 more but I see they are out of stock.
Excellent Phone Mount and this Twist-Lock version is far better than the Spring Loaded version.
It's actually easier to get phone in/out and holds phone more securely.
