This mount is everything I was wanting. Very rigid and yet easy to manipulate to the position I prefer. It looks like it is very well made and should last a very long time.
Worked with the Tackform staff to custom fit a tablet mount on the center console for our grand daughters. Quality product and quality service.
Purchased the iPad mount and headrest ball clamp. Product shipped fast. Ended up I ordered the wrong extension piece. Customer service was amazing to deal with. Shipped me the return label with the correct extension piece and I had it before the end of the week. I’ve recommended them to several friends !!! Amazing product quality
