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 Much Fun! High Quality & Perfect Alexa Smart Integration.
Color: Black
I use these Govee RGBIC Light Bars every single day in my room, and they have completely upgraded the vibe of my workspace. If you want to add some serious personality to your setup, these are an absolute must.
The fit is perfect right behind my monitor, completely transforming the overall appearance of my desk area. I have them seamlessly connected to Alexa, so all I have to do is say, "Alexa, turn on my Govee lights," and they click right on. While you can use a remote control or the app, the voice activation makes them incredibly convenient.
It is just a lot of fun to play with the different settings. You can change the colors instantly to give the room whatever mood or feel you are in the mood for. The build quality feels solid, and after months of daily, continuous use, the durability is excellent with no flickering or dimming. It has truly added a new level of enjoyment and style to my office space.
PROS:
High-quality appearance that makes any desk or TV setup look professional
Tons of fun color combinations and dynamic mood settings
Flawless smart home compatibility with Alexa
Great durability for daily, long-term use
CONS:
There are so many features and color modes in the Govee app that it can take a little bit of time to learn where everything is, but it is worth it.

Cool light bars
Color: Black
Lights work great. Easy to install and connect to the app. Endless color options and they fit perfect on my desk. I stuck two of the behind my monitor and two on the side to make nice ambient light. I like that you dont need the app to turn on the lights.
