VizGiz 6 Pack Tightening Nut for Replacement Car Mount Screw-On 17mm Ball-Joint Fixed Adapter Head Bracket Holder Ring for Phone Air Outlet Handlebar Kit Camera DVR Camcorder Wireless Charger

It actually come with two different sizes and the smaller size fit great. I would recommend this product. Thank you!

Worked perfectly to replace a broken locking ring on an ESR phone holder.

Product information indicates it should fit a 17mm ball joint but this product does not.

I assume the bad reviews are only because it didn’t fit their specific product. These work perfect and tighten great for mine. I found the perfect phone stand that doesn’t break, so sure enough the only thing that breaks is these. That’s because they deal with the most tension/friction. Which is way better, and cheaper to replace, than the entire stand snapping in half every time after less then a year.

These all got one star due to them not having anything to do with suction power, Camara quality, and sturdiness. Thay did work yes

I wish that this came in a smaller package size, not exactly sure what I’ll do with 6 of them. But I’m sure if my phone holder broke once it will break again and I’ll be thankful I have it later. Was concerned it wouldn’t be the correct fit due to other reviews but I can say it definitely fits the vanmass car phone holder tightly where the prong doesn’t move at all!

I have an iOttie Easy One touch 5… None of the nuts would not go on as intended, and were all too tight. All 6 screwed on without the ball, but I was only able to get 1/6 on with the ball in the socket. This required my entire body weight to get it into the slot. It does technically work, but it definitely wasn’t perfect.

I broke the piece that held my phone holder together. This was a great solution to fixing it.
