ToughTested Boom カップホルダー タブレット＆GPSマウント

The expandable base fits snugly in my truck's cup holder and doesn't budge even on rough roads. My 10-inch tablet sits at eye level without blocking the windshield, which is exactly what I needed for navigation.

The extension arm actually reaches my dashboard without blocking the windshield, which was my main worry. It holds my 10-inch tablet rock steady even on bumpy roads, and the expandable base fits my cup holder snugly.

The expandable base actually grips my car's cup holder tight, so my 10-inch tablet stays put on bumpy roads. Only gripe is the arm wobbles a little if I extend it all the way out, but kept shorter it's rock solid.
