Original review:
Received it today, packaging and everything seemed perfect. Looked over all the pieces and they seemed OK. Took a bit to assemble but not bad.
The design and construction are great. It looks awesome for my setup as you can see in pics. Really love this, or at least what it's supposed to be if everything was perfect. However, once assembled, upon closer look, I was just so disappointed. I just couldn't believe it. The bottom shelf on the left side is pretty messed up (refer to pics). Also on the right side but not quite as noticeable. Not sure what to do here, I don't think I can deal with this especially at the $100 price point. If it was in the back, I wouldn't care too much. But of course it's right in the very front just staring at me lol... I'm pretty bummed out, probably returning this unfortunately.

Fits amazing!
Color: Brown, Color: Brown
Fits just right, like a glove on my desk. Make sure you take measurement on the width, it is long. Saves a lot of space. Easy to assemble, but make sure you’re aligning the front with the front on the 1 & 2. Sturdy, amazing quality.

Terrible Quality Control
Color: Oak, Color: Oak
A piece of the wood didn’t even come punctured. Unable to assemble this. Waste of time and money. Avoid at all costs.

Great Tray For Storing My Everyday Carries
Size: 8.5" x 5.8" x 1.9", Color: Black
My everyday carry items (wallet, keys, etc.), used to just get thrown around wherever when I'd get home, but this little tray makes a great, defined, space for me to keep those things when I don't need them on me. The soft lining reduces the obnoxious sound of throwing keys on a hard surface, and of course keeps me from scratching up a surface. The build feels quality and I haven't seen any damage to it yet. Also the all black version with gold buckle looks quite good and adds a subtle touch of luxury. Absolute recommend for the price.
