The Massive Valet That Elevated My Workspace
First things first: this drawer is massive! But in a good way. The UPERGO Desk Drawer Organizer Tray can be used either as an under-desk mounted drawer or a desktop valet-style tray. I use it for the latter. When I come into the office, I tend to drop everything into the valet tray, including my cell phones, wallet, keys, earbuds or IEMs, and other everyday carry items. I utilize multiple desks in my office, including a couple of L-shaped desks and a tech bench for hardware repair and product reviews. This desktop valet-style tray checks all the boxes for my needs.
Simply put, it transforms the workspace. It has multiple compartments for various items of different sizes. My cell phones fit in one space, my pens and pocket journal in another, and my watch in yet another. It's ideal for your EDC (Everyday Carry) items, for sure, and having that nearby helps declutter and save space on your desk. I aim to keep the top of my desk as clean as possible and utilize an under-desk tray for my keyboard. This setup is perfect when I need to write in my pocket journal on top of my desk or take top-down shots for any product review. Ideally, it's probably better as a tray under a large monitor stand, on a decent-sized nightstand, or mounted under a desk in a 3D-printed tray—but it performs exceptionally well in my use case as an accessible yet organized tray for my essential items.
The black steel/aluminum and walnut finish looks extremely good in any layout, even better if you already have other matching items from UPERGO's lineup, including their other desk organizers, pen holder, laptop holder, or headphone stand. If you don't already own any of their products or haven't seen them, I highly recommend checking them out. They are a great alternative to pricier options, and honestly, their quality is just as nice. I have multiple items from their lineup, and they all pair well together, keeping the aesthetic uniform, tidy, and elegant.
It has elevated what was previously a gaming desk to a professional productivity desk. The pictures don't do it justice, as I was utilizing this tech bench/product review desk for this purpose. However, they should give you a clear look at the size of this valet-style tray. This is precisely the point I want to emphasize: this tray is huge, and you must have the desk space for it if you're going to use it on top of the desk. Otherwise, it would be great for a nightstand or as a key holder for an entryway stand.
It is premium for its price, sturdy, and won't slide around much at all. I love its look and overall minimalist design. It keeps my items organized and declutters the area where I am using it. Considering its price point and materials, this is one of the best items if you're looking for a decluttering solution that also looks fancy and professional.

Perfect midcentury organizer
After spending literally hours searching for a catchall/organizer, I finally decided to get this one for my husband. I'm so glad I did. His dresser is much more organized and clean, fits vitamin box, colognes, glasses, keys, and complements the midcentury look of our home. I ended up buying one for myself to store my perfumes and water bottles.

Great Desk Organizer Trays!
I don't often post reviews on Amazon but these desk organizer trays really deserve a review. These are LITERALLY knock off of Balolo trays at a fraction of the cost with the same quality and craftsmanship as Balolo. I got them with the hope of been able to take the divisions out and glad that I did. Taken the divisions out to use them as paper trays is possible and it is super easy to do with a screw driver taking 4 screws from under the tray. Then you can use them as paper trays. I got 5, three I'm using them as paper trays and 2 as desk organizers. The small tray and the pen holder are also worth getting to complete your desktop/office setup.
