Review: Does the job perfectly however it does have cons - I have a flatbar bicycles and after alot of research i decided to get the quad lock with the flatbar adapter. I was very skeptical that the glue of the flat bar adapter and the rubber band attachment of the mount wouldn’t be enough to keep the phone in place but it has been a couple of months now and after a few gravel tours there eere no issues. The only problem i have is there is no much of vibration and I’m worries my phone camera would get damaged in the long . If you have a flat bar ib would totally recommend this product
