John D. (Flat Rock, US)
Perfect with large phone in a case

The new larger model fits the galaxy note 20 ultra in a large Otterbox case perfectly. The mounting system let's you adapt the phone for your bike. The customer service is outstanding. Second purchase, highly recommended, very secure and easy to use. Bike is a 2021 harley road glide

Center post bracket for sport bike

The design is very good and the fit is excellent and secure. The two different sized wedges were easy to interchange based on post size. There is enough adjustment throughout the bracket to allow for the phone to be placed in positions for everybody’s liking. Excellent product!

Christopher B. (Sydney, AU)
First class components. Brilliant customer service.

This 3.5 inch dual 20mm socket arm is one of several components recently purchased. The quality is as good as, if not better than anything available here in Australia. The perfect way to set up a reversing camera monitor in my 2009 Land Rover Defender without unnecessary drill holes in the dashboard. Customer service cannot be faulted. Brilliant.

Rob (Port Orchard, US)
Great quality!

Awesome craftsmanship, quality, and function.

Miguel F. (Buffalo, US)
Excellent product!

I bought this for use with my R6 as part of a custom order of pieces and the construction is excellent and it works very well.

I would recommend Tackform products for anyone!
