Greater than one weekPurchased to match up a different holder for a phone, using the bulletpoint mounting system. A little expensive for a small piece of steel but it’s life I guess

> 3 dayPleasantly surprised by the quality of the adapter. It is constructed of steel and has a textured finish on each on the 17mm and 20mm ball ends of the dog bone adapter. It worked perfectly!
