Well made and stylish riser for my sit stand desk.
Color: White, Size: 42.5 Inch
I got this to provide a place to tuck my 49 key Arturia keyboard. The only thing I wish they would offer is a taller leg option by 1 or 2 inches in height. Regardless this thing is a beast and will easily hold a wide screen monitor or dual 27” monitors and space to tuck your laptop underneath on the middle shelf out of the way. I happen to have my monitor on an arm to provide even more usable space on the top. I have a USB switch on the right middle shelf and room for my AirPods on the left with room to spare. My Apple pencils fit perfectly on the tray as well as my iPad. In order to make this work for my application I ended up getting some acrylic cubes and silicone bumpers and pads to raise the height by two inches so my 49 key keyboard would easily fit underneath. It turned out really well for the look I wanted. If the legs were longer I wouldn’t have had to take it this far. The color is pure white and matches my desk color perfectly. It was super easy to put together. It is very solid and has a durable easy to clean finish. All in all I have no regrets making this purchase. It is very functional even without the height modifications that were specific to my needs. I will come back with a photo or two once I get settled in my new place and finish getting my studio set back up.

Saved my neck and my desk space! Solid and stylish
Color: Walnut, Size: 42.5 Inch
I’ve been looking for a way to raise my dual 27-inch monitors, and this Fenge stand is perfect. The 42.5-inch length is exactly what I needed—both monitors fit with room to spare. It’s raised them to the perfect ergonomic height, so no more neck strain!
The wood finish looks much more expensive than it actually is, and the storage space underneath is a lifesaver for hiding my docking station and keyboard when I'm done for the day. It feels very sturdy and doesn't bow in the middle at all. If you want a clean, organized desk, this is the way to go.

Decent Stand with Lots of Storage Options
Color: Black, Size: 42.5 Inch, Color: Black, Size: 42.5 Inch
Received this stand today and am very pleased. I was able to put it together in about 15 minutes . I had no issues during assembly other than that my box was missing the instructions; luckily they were relatively easy to find online when searching the brand on google.
Now for the price range, this is a great bang for your buck as far as monitor stands go. It has nice heavy duty metal legs and the built in phone stand is a nice touch, but I do wish the the stand itself was made of solid wood as it does feel like cheap particle board that may or may not bow over time depending on how much weight you put on it. It's not as cheap feeling as many other stands on Amazon but I do think it would benefit tremendously if it was built with real wood.
Because it has (2) shelves, one of the best things about this stand is how many places it has to store items, setup docking stations, laptops, or even small music interfaces including under the bottom shelf. However, I think that the center cubby should've had an opening in the back to allow cords/cables to pass through which would've made this stand even more versatile, the only way around that issue is to drill a hole through the back panel but at least it will be pretty hidden and not visible from the front.
All in all, I'm happy with my purchase and think the pros outweigh the cons. It tidied up my desk's overall look, has (2) wide shelves, and overall sleek/modern design all for $100 makes it worth it. I would definitely buy it again but hope they improve on the shelf material, even if it does increase the price slightly.

As good as you hope it is!
Color: Walnut, Size: 42.5 Inch
I'm really happy with this stand! It perfectly well made, all the holes line up, the legs are made of metal, it's very sturdy, and the instructions were easy to follow! The stand sits on my desk perfectly flat and the wood print veneer looks good. I would recommend this stand to friends and family without hesitation.
