Did not have Adequate instructions. But , not to hard to figure out. I have only had the Q- mount installed for 3 weeks . It works great so far .
Best I ever found, works great!
Used this adapter, along with an old water bottle holder clamp, that I modified to fit the grab handle in my Jeep Gladiator. Drilled/studded/epoxied a 1" plastic ball bearing to the old mounting clamp and attached the adapter arm and phone holder to it. Shweeet !...and rock solid!
Shipping was fast and quality seems good. I havent had a chance to use it very much yet but i think it will work well.
My Q Mount pro now fits perfectly where my TomTom Rider used to be.
only used once. seems to work well. needed something to mount and dismount one handed. Fits the that need.
