Travel tray: the understated rock star
This should be called "the little wonder" because it is so simple but so helpful.
I used it on my recent trip and it sped up my process through security so much that after I stepped away from the Security area, I stopped to make sure I didn't lost anything. It was so fast and easy.
I just threw all my little items into it when going through security and picked it all up on my way out. While I by hotel, I put my watch, Fitbit Flex, and my phone into it so it was always in one place.
My dad, who travels a fair amount will definitely be getting one for his birthday.
