OOKUU Upgraded Large Desk Cup Holder Clamp, Anti-Spill
Our verdict: A sturdy metal clamp with a deep cavity for big tumblers.
The OOKUU uses a large-diameter metal clamp with a deep, form-fitting cavity, and installs without drilling, in the under $25 bucket. Depth is the underrated spec on a cup holder. A shallow cavity lets a tall tumbler tip as soon as someone brushes it, while a deep one holds the base and part of the body, so the cup stays upright when an elbow catches it.
It takes first place by combining a metal clamp with that depth for oversized drinks. The plastic holder further down gives up the sturdiness that matters when a full tumbler sits at the desk edge.
Buy it if you carry large tumblers or insulated bottles. The caveats are that exact diameter is not in our facts, so check it against your cup, and that the position is fixed, so there is no way to swing it clear when you stand.
