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.

So immersive, easy to set up and affordable it beats our Phillips Hue set up!
If you want a stunning, immersive viewing experience this set it for you! It can sync with up to 5 Govee light strips or bulbs for and even more immersive experience too! We have 3 different Govee backlight set Ups and this is the best one. It levels up our gaming experience. I cannot imagine watching movies without one now. Theater experiences are lack luster in comparison. Definately watching their how to videos on proper set up and syncing using those funny orange foam pieces! It makes things so much easier! The difference in the color displays are amazing! We synced 3 Govee rbgic light strips and two govee bulbs to the system. We get so many compliments on how incredible the room looks. When combined with relaxation, music or oled videos it's like a sanctuary! It is better in some ways than the Phillips $500 Hue set up we have on another set. It's a good idea to leave some of the adhesive spots on the led strip unused and covered in case your TV dies or you get a new one. This adhesive strip is strong and not reusable. Our new TV died during a power outage. This strip came off fine but lost all it stickiness once removed. Hopefully you won't ever have to remove yours. This is definately a 100 out of ten for us!

Great lights
Gorgeous lighting, it syncs perfectly with the tv colors and when the tv goes dark the lights go off, very cool effect. Happy purchase.
