Pretty good

I was super happy to get this! So I wanted to make a good review: an ACTUAL review. I took it down a few trails, highways, county roads, etc, so here is the good and not so good/needs work.

-Pretty stable considering the coil.
-fits 12.9" iPad with case.
- great quality!

Not so good:
-Hardware to mount to the seat post didn't fit well, so I had to adapt and overcome.
-lock washer was too big and couldn't be used.
-fair amount of movement on trails in the coil.

- attach a hook and loop tether for some stability.
- review the mounting for 21+ jeeps
- stiffen the coil or have an additional strength coil for the upper portion of the armature.

All in all, this is really pretty darn good! A few things here and there were "meh" but nothing stopped the functionality or performance. It is easy to use, easy to move, and even as a 6'0 285lbs guy in the passenger seat, it was out of the way! Good job!

Love it

I have used this in my truck for years. I love it. It even has the same bolt size and thread as the seat bolt in my F150, screws right in, no extra hardware needed.

Good so far

Just installed the other day works great

2022 Subaru ascent

We were looking for a back seat center tablet holder for my kids to watch movies on long trips. This was not tall enough (it sits center console height) and the arm moves significantly every time we make a turn (despite being tightly installed at the back base of the passenger seat). I was hoping for something taller and more rigid. It’s nice quality but not working in our vehicle for our need.

Love it

The mount was a lot heavier then I thought it would be. Hold my 12' tablet perfect !!
