Review on TACKFORM Chrome Motorcycle Mount: Enduro Series Rock Solid Holder for iPhone and Samsung Devices - No Slings Required! by John Ortiz

We bought three of these and we have different phones. The bracket on them is spring-loaded, so it securely holds any size phone. They are easy to install and easy to move when needed. I have full confidence that my phone will not fall while riding a motorcycle. We mainly drive on motorways and country roads, rarely cross-country.
