Make sure you get the correct size ball mount for your application

The size is pretty flexible, but I wouldn't use it for very large phones like the Galaxy Note.

Use on multiple motorcycle and holds phone great but can’t handle size of iPhone 10xr in otter box defender but works on smaller phones

This is the right size for a larger phone

Its the right size

great product but the next size up would hold way more devices

I was looking at a ton of different options, but considering the "bulky" size of my phone, this unquestionably seems like the best option out there, as of now

Be sure to get the right size for the device you're going to use with it.

Good size for the Samsung Note 4 (ancient phone but still works great)

Love it Perfect size

Just make sure to he the right size .

This size fits the 7+ much better

This size works fine with my iPhone 6

This is the smaller of the two sizes available
