Looks great, LED strip is a nice touch. The unit is relatively lightweight while still being quite sturdy. There were a lot of parts and it took some time to assemble, but the instructions were very clear - just step-by-step drawings but everything was labeled clearly. I was pleasantly surprised that the hardware that is used to put it together is better than you’ll often find with low-cost shelving and furniture too, which gives you confidence while assembling. Just don’t over-tighten anything to avoid cracking or stripping the parts.

Nice product, wall mounting could be easier

Size: 7.9"D x 39.4"W x 34.3"H, Color: White

Easy to put together, nice finish. Missing a star cause mounting it to the wall is a lil more difficult than it should be. I would never use the wall anchors to mount this

This is an amazing product, It holds quite a bit, very durable and I havent had any trouble with it besides the led lights that are on the top wont stick. Other than that, its very easy to use and can hold alot of weight.

Looks amazing! Perfect Gift

Solid shelves however the instructions were really difficult to follow even with three people helping. Looks absolutely amazing so it deserves 5 stars.
