I like the tray a lot. Quality is very good. Color (Brown) is attractive. Size is perfect for my nightstand. It holds phone, remote, eyeglasses, & phone. I threaded my phone charging cord through a corner of the tray. But it slides too easily off of the nightstand. I'm going to try to find something to stop it from sliding that will stick to the underside of the tray without harming the wood surface on my cherry nightstand.

Better than other flimsy trays
Color: Black, Size: Rectangle, Color: Black, Size: Rectangle
I got this to replace another flimsy valet tray I got as a gift. This one is way more sturdier, looks nicer, bigger, and has a nice feel.

Looks great, doesn't hold much so measure carefully
Color: Gray, Size: Rectangle
I got this organizer for my husband to keep his stuff by the door. While it's a little smaller than I'd hoped, it looks great in the entryway. It's super easy to snap together, but feels like the material could be damaged easily if you're not careful. He is able to store his keys, wallet, and sunglasses in it, and throws hit hat on top. Overall we are really happy with it.

Perfect
Color: Blue, Size: Square
Just what I needed. The size is perfect as I didn’t want anything too large to place my watches and other accessories inside near the corner of my desk. Its size is essentially 7x7, and the design is sleek compared to other organizer holders. I got the color in blue and it looks stunning with the rest of my setup. I’m unsure about other reviewers, but mine came safely and the leather walls are decently thick, so it’s not too flimsy when buttoned together which holds very securely. There are hole spaces at the bottom corners once assembled, so if you have super small items such as beads or really small jewelry, they could potentially fall out, but most of my items are large enough that won’t be of concern. If you have a wire charger near by, the holes could be used to charge your smartphone inside, which has its own practical usage. Overall, I’d definitely recommend it if you’re on a lookout for a sleek but compact organizer holder, and I personally will consider getting another one in the future for myself for other household belongings.
