Shelving unit
Style: 5-tier Vintage Industrial
This is a very nice shelf. It’s made really well. It was easy to put together and attach to the wall. Fit perfectly where I wanted to put it. Shipping was fast

Sturdy, secure, well-crafted, and gorgeous.
This is a dark photo but I ordered this for a safe and beautiful space to keep the ashes of my past pets who meant the world to me. It is true to size, holds weight exactly as described, easy to assemble, and securely mounted with everything you need included - they even send a magnetic screwdriver for you.
The variety of lights colors and modes are exceptional, and there are dimming features and many permutations of light sequences and patterns you can choose from if you want to give it an automatic setting. It's a perfect final resting place for my pets where I know they can be honored beautifully for the rest of my life. Recommend this purchase for any project on your list requiring a shelf with a lighted back. The hanging hooks and lower bar are an added bonus. High quality product, very versatile, and amazing value.

Faulty pieces, unable to assemble.
One of the pieces came unthreaded so I wasn't able to put it together. We received all of the parts but since one was faulty, assembly wasnt possible. Customer service from both the original seller and amazon were unhelpful. Wish I could get a replacement part because I was really looking forward to this in my kitchen to add to the coffee bar, but I'm going to have to return it.
