Great portable, adjustable phone/tablet holder
I finally traveled by plane to test this out. First, I love how slim it is when flat, so that you can easily slip it into your backpack or purse. The silicone coating is grippy so that the holder and the phone are less likely to slip. It’s thin enough to slip in the gap between the locked upright tray table and the seat back, so that you can hold the phone closer to eye level for less neck strain. It also sits securely on top of the pulled-down tray table. It’s able to hold a cell phone or a tablet. With a little help to avoid slipping, it can even prop up a heavy portable monitor.
One drawback is that when it is hanging off the back of the tray table, the phone can slip off the side of this holder. It slipped out on take-off. Even so, this is my favorite travel phone holder so far.

Phone Stand
I love this unique phone stand. It’s easily bendable, and large enough to support a phone or tablet, while still being small enough to be portable.
