Great product!

I bought this mounting arm as an interface between my Honda Africa twin motorcycle fairing and my GPS mount. So far it is working flawlessly. I highly recommend it for anybody who needs to go from a 20 mm ball to a one inch diameter ball.

So far so good.

Does as expected. Everything tight. Hopefully it remains so.

Excellent mount.

Holds phone very tight, even with Otter box case on it. Rubber safety strap not needed. Have mounted on my 2015 Harley Street Glide. Will be ordering another one for my other bike soon.

Excellent Phone Mount

Worth every penny. Well constructed, easy to install. Phone stays in place with or with extra strap. Zero complaint!

Great phone holder

This is a great phone holder. What drew me to this one was the one-hand use. Take phone out and put phone in with one hand.

Rock solid!

Best mount I've ever found. Installed on my 2016 BMW R1200rt, I have every confidence this will be the last mount I ever need. Fantastic product.

Awesome - less than 5 minutes to install !

Works great. I put on my Fat Boy with custom bars. Don’t need the rubber to hold my i-phone . Would love it in chrome!!!
