Just lovely
Size: 8.5" x 5.8" x 1.9", Color: Orange
Purchased this several months ago and liked it, but I had received so many complements on this tray since then I had to submit this review. The tray is sturdy and put together well, and the size is exactly what was given before purchase.

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.
