The Ideal Organizer
The UPERGO Valet Tray is an ideal size for my nightstand. It does not slide around but stays put where I position it. Each section is useful for the items I want to keep close at hand but in an organized fashion, cell phone, wallet glasses, change, etc. I love the cork interior of the tray; it’s stylish and functional.

It's a functional organizational tray
I bought this valet tray for my nephew to be able to organize his go-to items, such as his cell phone, wallet, watch, bracelet, etc. I expected the tray to look more upgraded. The compartments are shallow, but they do the job. It is made of a cardboard-type material ( corkboard would have been nicer), and the black platform is a metal construction, which gives it a more stable and solid structure. Overall, for the price and its functionality, I guess it was worth the purchase.
