I used this holder to mount an iPad mini in my Big Horn as a convenient car navigation system. I removed it when I replaced the car and kept it. It's built sturdy, and it's "too good to waste," so I'm listing it for someone else to use. The bottom is secured with double-sided tape, but I couldn't reuse the old tape, so I removed it and replaced it with "magic tape (Pital)." Please clean and dry the adhesive surface before applying it all at once. I've included the instruction manual for assembly and installation. Also, there's a QR code in the instructions for an installation video. Please watch it if needed. The following is part of the seller's description from Amazon: * Car mount holder with super strong adhesive gel + vacuum suction cup, strongly adheres to the dashboard and is difficult to detach or sag! * Car tablet holder for car navigation iPad Air mini Pro Kindle Fire Paperwhite.
