I think this tray is a good value compared to other vendor's products that are $100+. I plan to keep it because it is a good value for me. HOWEVER, realize that the metal base does not extend across the full base of the cork liner. Metal pieces are only on the edge of long side of the liner. Also, the metal is lightweight.

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.
