The ART-GIFTREE Clamp On Desk Shelf is a two-tier wooden shelf that fixes to the edge of a desk with two C-clamps, so there’s nothing to drill[1]. It fits desks from 0.4 to 2.28 inches thick, mounts above or below the desktop, and holds up to 30 lb[1].
Key facts
What is it?
A small two-shelf unit with wooden shelves that clamps to the back or side edge of a desk. ART-GIFTREE pitches it for office supplies, books and gaming gear[1]. The point is to use the space above the desk instead of the desk itself.
This review covers the 16.5-inch, two-tier version in brown. The same Amazon listing sells a 12.5-inch two-tier version in four colours, the 16.5-inch in black, and a three-tier version[1]. Their sizes differ, so check you’ve picked the right option before you order.

How big is it, and how much does it hold?
It measures 16.5 inches long, 6.85 inches deep and 16.85 inches high[1]. Amazon’s product table elsewhere on the page rounds that to 7 × 16.5 × 16.7 inches. It’s the same shelf, measured to different precision.
The rating is 30 lb in total, 15 lb per tier[1]. That’s fine for a router, a hard drive dock, a few books and a headset. It isn’t a monitor riser for anything heavy. The shelves have adjustable dividers, and you can leave off a tier if you only want one[1].

Will it clamp to my desk?
If the desktop is between 0.4 and 2.28 inches thick, yes. The two C-clamps tighten by hand, with no tools and no drilling[1]. Like any clamp, it needs a solid, flat edge with clear space underneath. A desk with a deep frame rail, a drawer right at the edge or a rounded lip may not give the clamps a good grip.
It can also hang below the desk instead of sitting on top[1]. Underneath is a good home for a power strip, a laptop dock or the box of cables you’re definitely going to sort one day.

What’s in the box, and how long does it take to set up?
The listing’s video shows two wooden shelf boards, L-shaped brackets, the clamp hardware and screws[1]. So expect to put it together before you clamp it on. The clamps themselves need no tools[1].
What would a developer use it for?
Getting the small stuff off the desk. A Raspberry Pi and its power supply, a USB hub, a notebook, the test phones, a game controller. Mounted below, it can hold a dock or power strip so the cables stop draping across the desk.
At 6.85 inches deep, it’s too shallow for a laptop to lie flat, and 15 lb per tier rules out a heavy monitor[1]. Treat it as storage, not a stand.
What we couldn’t confirm
ART-GIFTREE doesn’t publish a product page or spec sheet that we could find, so everything here comes from the Amazon listing. It doesn’t give the gap between the two shelves, whether the clamps have pads to protect the desk, what the frame is made of, the type of wood, or a warranty[1]. If you need a particular clearance between shelves, or your desk marks easily, ask the seller first or put a scrap of felt under the clamps.

Pros and Cons
Pros
Final Verdict
Get the ART-GIFTREE Clamp On Desk Shelf if your desk has a clear edge between 0.4 and 2.28 inches thick and too much small stuff on top of it. It adds two shelves without drilling, above or below the desk[1]. Look for a sturdier riser if you want to put a monitor on it.
