As a quad lock user for over 5 years, I suggest to add small anchors/hooks around corners of the mount for zip ties to further secure it on stem. With the adjustable design of the mount + the weight of phone, the phone vibrates and swings around too much during the ride.
I’ve bought multiple bar/bike mounts and they are all such a pain to get my phone in and out of, this process is streamlined and secure! I want to buy 2 more!
This is such a great mount for a bike. And I love how strong it is. I don't need to feel worried my phone is going to pop off like most other bike mounts. And this would also be a great bike mount if your'e traveling and going to rent a bike. So easy to just pop on any handle bars
I just got this, as part of the kickstarted campaign. I’ve mounted it on my handlebar stem that holds the bars. It works great, even thought the stem is somewhat thick (aluminum). The attachment is solid. It does not take up much room. It is the best phone/bike mount I’ve ever used.
