Our roads are BAD!

On our streets and on the highway the phone did not move at all, on a very rough road with pot holes it did wiggle a bit but stayed in place

Very stable even on bumpy roads

The only slight issue I have noticed is the holder will jiggle a little on rough roads

Lots of off road and rough road use

It holds my personal Samsung J3 in a bulky case, my work Samsung S7, S8 and Google Pixel in waterproof cases and my small GPS perfectly, even on rough roads and construction driveways, the device can easily be inserted and removed from the holder with one hand, and connection cables do not get in the way

Enough room that if you needed to toss some coins in for parking meters or a toll road ticket.

Works as it says

I rated one star less as it doesn’t stick firmly on my Audi Q5 dashboard, I wouldn’t complain much as it stays in place and doesn’t move with speed

I’d highly recommend this holder as it helped solve where to put our phone.
