All Metal, easy to fit. Holds phone very securely. You may need a 5mm longer stem bolt!
Stem mounted, all metal construction. VERY easy to fit. (I did need to buy a 5mm longer stem bolt!) Designed to be functional, and it works very well - included Allen key locks everything in place once you get the position how you like it. Holds phone very securely, not seen much vibration being transferred to the phone. 100% recommend this mount, I’d buy again (but don’t expect this to break!)

Easy to install, performs solid, no wiggle, exactly what you want.
Solid, easy to install and a HUGE upgrade to my last phone holder which was strapped to the middle bar and not nearly as easily viewable or accessible. This is secure, stable, easy to view and easy to interact when needed! Also easier to install than I anticipated.

Solid Mount
Quad lock products are very well made and last a long time from my experience. I’ve ridden a little over 1000 miles while using this mount on all different terrains and whether. Id say it works well as intended when the phone is mounted. I appreciate the location of the mount being on the stem despite needed a longer stem bolt, nothing a quick trip to the hardware store couldn’t fix. I also like the arm motion moving up and down. The arm seems to hold tightness for a while before you have to re-tighten to your desired resistance. The phone case is generic looking which was a plus for me and it’s held up nicely and works well with my MagSafe chargers. My biggest issue with this system is actually attaching the phone to the mount. While riding the bike it’s nearly impossible to get it lined up and twist into place. I find myself just sliding my phone all around trying to find the exact spot that’s required for the phones case to get into the groove of the mount so when you turn the phone it clicks into place. Even standing still most of the time I have to bend down and look underneath just to line everything up. I really think quad lock missed the mark on this part. It should be as easy to put on as it is to take off. Overall, this mount and phone case will last a long time. For this price point you’re paying for the top notch quality from a good company that should work for a long time. If you have the the money to get into the ecosystem I think you’ll appreciate the craftsmanship.
