Excellent value.
The instructions were pretty easy to follow. I appreciate that there was an extra screw of each size provided, just in case. I wish there had been clearer indications on how to handle the cord or the included light. I ran it down the inside and mounted the switch on the inside of the display shelf.
I bought the white variant; however, beacause I am not fond of black furniture and tend towards bright colors, I used blue spray paint to cover the black metal and make the piece better fit my decor. A white with white option would have been ideal, but now I have a unique piece so it all works out.
The value for the price is excellent. It is a large, sturdy piece that should prove functional for years to come. I am considering purchasing a second one for my husband's gaming space.

Looks great
The assembly instructions were clear and well done. Parts are all well made and holes were precision drilled. Very happy with this product.
It is heavy enough that mounting it on the wall is a chore. I strongly recommend you measure the holes and mark using a level and install your anchors - I used the white screw-in ones.
The control app for the LED strip doesn't have a good rating. I have to tap it a few times to get it to engage but it works.

Very solid and well build gaming shelf
Solid materials and great finishes on the wood and steel. Simple assembly and comes with extra hardware. Very sturdy.
I got this to get my boys ps5 up on the wall and tucked behind the TV. I absolutely love this!!!
