Every question, answered.

That's the surface it's built for. Hard, flat surfaces are the easy case — the wide base and the fin grip hold at least as well there as anywhere else, vibration included. It settles in on the desk, the rack top, or the console the same way.

That's the actual test in this room. The wide base spreads its grip across the desk instead of balancing on a point, so a bass-heavy pass or a nearfield humming next to it settles the drink back instead of walking it toward the edge.

Measure the bottom, not the rim. A base of 2 to 3 inches across settles in — the 40 oz Stanley does. Handled mugs don't; the handle lands exactly where a fin needs to grip.

No. Nothing clamps to a tube diameter, a desk edge, or a mic stand. It sits on top of whatever's flat — the desk, the console, an amp, the floor — and works the same on all of them.

An open drink is still an open drink — nothing changes that near electronics. What this does is resist tipping in the first place: it holds steady through the reach, the vibration, and the rolling chair that usually causes the spill.

Yes — it holds the same way on an amp top, a rack shelf, or the floor by the mic stand. The surface changes; the base and the fins don't.

It's small enough to sit just inside the booth instead of out on the floor by the mic stand, so the tea or the water bottle isn't riding the headphone cable on every trip in and out.

Rinse it under the tap or wipe it down — skip the dishwasher; heat is the one thing not recommended. It's one piece of molded material with no seams and nothing to come apart, so there's nowhere for a coffee spill to hide before it heads back to the desk.

It's called the Steadi — molded in small runs in Orange, California by Steadi Labs, veteran-founded and patent pending. Free shipping on every order from steadilabs.com, with 30 days to send it back if it's not for you.

It's one piece of injection-molded flexible material — no clamp, hinge, spring, or fabric insert to work loose the way clip-on trays and stand-mounted holders do after months of use. There's no seam for grime to collect in and nothing mechanical that can wear out; it's the same molded part on day one and day five hundred.

No — the grip comes from the fins flexing around the container's bottom inch, not from a spring or a temperature-sensitive clamp, so it holds a throat-coat tea straight out of the kettle the same way it holds an energy drink can straight out of a mini-fridge.

It rinses clean under the tap, and it's a single molded piece with no seams for a spilled latte or a sticky energy drink to hide in. The gear sitting next to it doesn't get that same treatment — a sugared spill in a fader slot or across a set of contacts is what actually causes lasting damage in this room.

One at the mix position covers the desk, but it isn't the only surface a drink needs to leave. A second inside the vocal booth means the singer's tea stops making the trip out to the floor by the mic stand between takes, and a third on an amp top covers the live room during rehearsal — three different surfaces with the same underlying problem.

It works well as one because it doesn't need to match anyone's setup in advance — no tube diameter to check, no desk edge to measure before buying. It sits on whatever's flat in whatever room the session happens to be in, so it's useful before you know a single spec of the person's actual desk or console.

A clamp-on holder solves exactly one surface: the stand it's sized for, and only if the tube diameter matches. It does nothing for the desk, the console top, or the vocal booth. This doesn't clamp to anything, so the same one moves from the mic stand to the desk to an amp top without needing to match any of them.

Rack space is a standardized 19 inches wide, with one rack unit (1U) equal to 1.75 inches, so even a shallow 1U or 2U shelf has more than enough width for a base in the 2 to 3 inch range — the fins flex to seat bases as wide as 3.15 inches — without hanging off the edge.

Yes. The physics that cause the tipping — a vibrating desk from the monitors, one crowded surface, a reach across it toward the mouse or the interface — are the same whether the room is a full commercial console or a bedroom desk with an audio interface and a pair of nearfields. The base and the fins work the same on either one.

Both are inside range, just at different points in it. A sleek 12 oz can — the shape Celsius, Alani Nu, and most slim seltzers ship in — runs about 2.25 to 2.3 inches across the base. A standard 12 or 16 oz can, the shape Red Bull's and Monster's larger sizes use, runs about 2.6 inches. Even Red Bull's smallest 8.4 oz slim can, at roughly 2.1 inches, clears the 2-inch floor.
