Review on Tryone Car Headrest Tablet Mount Holder: Stretchable Stand For IPad Air Mini/Cell Phone/Galaxy Tab/Kindle Fire HD/Switch Lite 4.7-10.5" Devices by Runbi Alvarez

Fantastic tool for road trip for the back passengers. Big enough to accommodate a big phone (length) or a medium size tablet (width). We used it quite a bit on our recent road trips and the kids loved having a movie theater in the back (tablet with portable bluetooth speaker). The adults get to enough our own music up front (car stereo with front speakers only). The retractable arm are surprisingly strong and hold up the device without shaking while driving. I would like the arm to be a bit longer but that might make the device shaking. I guess it's a happy medium.Retractable arm folds so the whole thing can be tucked away when not in use.DO be aware of how wide (or how narrow the headrest posts are). In our car, the headrest posts are too narrow so I have to take out the rubber pads in the clamps so I can squeeze it in. It's not the devices' fault. I think the headrest posts are exceptionally narrow so I either have to modify the item or I wouldn't be able to find one that actually fits. All is good.5 stars
