Universal Smartphone Phone Cellphone Holder Mount Attachment Tripod Screw Adapter

very stable, holds my phone on my bike.

I used this to attach my phone to a mount on my ride on lawnmower - and cutting the grass for 3 hours over quite bumpy ground it all stayed in place perfectly. Very pleased with how well it worked (and how it didn't drop my phone causing it to be eaten by the mower!).

Works great for my use case, but have found the part which you tighten up with the screw can be a bit brittle, and has cracked on one of them, still works fine though and holds well.

Holds phone really well but it's tight to get my phone in but then again I like it tight.

Phone holder which attaches to my already installed Camera (go) mount.
