                Surprisingly Amazing!
                Color: Walnut, Color: Walnut
                I bought this expecting it to be a cheaper product I would use until I bought something better. I was very surprised to see how nice it was! Very solid and non slip surface on the bottom. The wood on it looks great and one of the most awesome things about it is you can manually adjust it to fit your laptop. I have a heavy16 inch MacBook Pro with a case on it and it fits perfectly in this stand, after adjusting it, of course. I ended up buying another one for my work office too. I can’t wait to try other products from this company.

                INCREASED DESK SPACE - ORGANIZED
                Color: Walnut, Color: Walnut
                I just received my new Vertical Laptop Stand by UPERGO! I had no idea that this device could free up so much space on my desk! AND, it looks great, very rich & professional with the solid wood, Walnut dividers. It has solid weight so your laptops won't just tumble or slide away either. The dividers that hold up to 2 laptops will also hold your cell phone. What an clever invention by UPERGO! I am now able to keep both of my laptops in the same space which frees up substantial workspace for me. The feature that allows me to adjust the width for different sized laptops is GREAT. I was at wits end how to add ventilation to my laptop as it became so hot. It now runs much, much cooler because the fan/air flow is vertical as opposed to flat on my desk. So many improvements in just one device. Thanks to UPERGO for this fine device which makes my desk look better & so much more functional! I highly recommend to anyone that spends time with laptops at their desk!

                Attractive and Solid Laptop Stand
                Color: Walnut, Color: Walnut
                The premium quality at this affordable price is a great deal to me. You'd see these sort of designs sold on high-end desk organization companies at expensive ($$) prices. In addition to being aesthetically pleasing, this is a solid laptop stand that was built with the utmost attention to detail. The walnut panels are lined with scratch-resistant felt pads while the aluminum base has a silicone cushion to protect your devices when placing them in. The silicone feet and sturdy weight prevents the stand from moving and tipping over. The adjustability feature is great, especially if you want to accommodate several devices or even books. Per its specifications, I find that it accurately accommodates items ranging from 2cm (0.7in) up to 4cm (1.5in) in width. It fits my 2020 Macbook Air 13" perfectly.
