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.

Great organizer! No more lost stuff!

We bought this for a friend who was always misplacing his keys, badge, wallet, etc... This has helped him get his every day carry stuff organized and he has not "lost" anything since.

Good value, but buyers should be aware that the metal base extends only on edges

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.
