I bought this hoping it would work on the grab bar of my 08 jeep wrangler. Jeep specific mounts are ridiculously expensive. I'm very happy this fit perfectly. It comes with a qr code which I'm guessing has instructions but setting it up was pretty simple so I didn't need it. Ymmv. It comes in 2 main pieces, a mount and a phone/tablet holder. It did take a good push to snap those together. One side is spring loaded to hold the screen in place. The other side is fixed but has a button on the back you can push to expand it in & out making it very adjustable. I tried it with a phone, back up camera screen and mini tablet gps & it fit everything. It does not interfere with the glove box below it thankfully. It's plastic, but feels very solid & well made. There is plenty space for chargers. It has a bolt hole on top that appears to be a go pro mount I think.
I hope it holds up well on trails. I've broken mounts before, time will tell.
