Tackform 20mm Aluminum Ball to 17mm Ball Adapter Compatible with Garmin and Other GPS Devices with 17mm Balls

Works perfectly for the application that I needed very stable fits my mounting options would definitely recommend this product

The 17mm is the old Garmin size. 22mm is the new size but this a 20mm which fits who knows what? Its made well but...

Works good use it in the work vehicle and person

I recently bought some Bulletpoint mounting systems for two of my vehicles. I already had a charging phone holder I still wanted to use but they didnt fit the Bulletpoint system as it came. I needed these adapters and they worked perfect. They have held them great and Im very happy with them.

Used this to join a generic MagSafe mount with my Bulletpoint mount in my Jeep. Worked out well and the metal construction vs. the plastic found on others is way better.

I mean...its a metal bar w/a metal ball on either end. The only way it doesnt work is if you didnt have the size right. Thats on the customer.

Solid, quality construction. Fit my Garmin GPS perfectly! Buy with confidence!

Great thing is this is exactly as advertised. Fits perfectly for my GPS.

Bought this to add my Garmin unit to my Bulletpoint mounting system. Works as intended.

Need to be a little thicker. But if you add some rubber will work better, size is perfect
