Every question, answered.

That's the whole reason it's built this way. Grass and sand give a narrow can no fixed footing to stand on; the wide flexible base spreads across either instead of balancing on a point, and the fins keep the can from rattling loose when someone walks past. Bump it off level and it settles back.

The base is what matters, not the bottle. A bomber's base and a standard can's base both land in the 2 to 3 inch range that settles in; a full 64 oz growler runs wider than that and is better set down carefully and left alone.

Yes — a tallboy and a 19.2 oz single share close to the same base as a standard 12 oz can; they're just taller, which is exactly why they tip more on their own. Measure the base, not the height.

No. Nothing pushes into sand or turf and nothing clamps to a boat rail or a chair frame. It sits on top of whatever's under it — grass, asphalt, a deck, a cooler lid — and works the same on all of them.

Hard, flat, or moving surfaces are exactly where this holds steady — a wide footprint and a grip on the container's base resist the wobble a boat deck adds on top of everything else. It's not magic; a hard direct hit is still a hard direct hit.

It works at least as well there as on the ground — a folding chair's narrow armrest and a cooler's curved lid are exactly the kind of small, unreliable surface the wide base and the grip were built to improve on.

Yes — a party cup's base is inside the range that settles in. It drops into the fins the same way a tumbler does, gripped by the bottom inch instead of the wide, tippy rim.

Rinse the sand or the dust off, or run it through the dishwasher. It's one piece of flexible material with nothing to trap grit or come apart.

It's called the Steadi, molded in small runs in Orange, California by Steadi Labs. Every order ships free from steadilabs.com, with 30 days to change your mind.

No. The fins grip the can's base, not the sides where sweat beads on a hot afternoon. The seal point sits below where condensation collects, so a dripping-cold tallboy grips the same as a dry one.

A bump from a passing kid or dog is exactly the kind of hit the wide base and the fin grip are built to handle — the base flexes with the nudge and the drink settles back level instead of carrying the tilt into a fall. A direct kick or a full step on it is still a direct hit; nothing changes that.

Usually not. A thin foam or neoprene koozie — a "stubby holder" in Australian slang — adds only a little wall thickness, so a koozied can's base still lands close to a bare can's roughly 2.6 inches, inside the 2 to 3 inch range that settles in. A rigid double-wall can cooler adds more real width; stand it on a sticky note before assuming it seats, same as any other container.

One holds one drink at a time, same as any cup holder. A tailgate lot or a cornhole game usually has several cans and cups in play across the group at once, so most people using it at tailgates or campsites end up with one per person rather than one passed around.

It's built to answer more than one of those on its own — the same base takes a can at the tailgate, a bottle at the campsite, and the cup off the keg at a party, so it isn't a gift that only covers one of someone's hobbies. It comes in a few colors and needs no setup.

Insulated can coolers with a stand are sized to one can's diameter, so they solve the wobble for exactly the drink they were built around and nothing else — swap in a bottle, a bomber, or the cup off the keg and there's nothing to hold it. This isn't sized to a can at all; it's sized to the 2 to 3 inch range that most of what beer comes in actually falls inside.

No. It's one piece of molded flexible material with no hinges, springs, or hardware to seize or work loose. Toss it in the cooler bag, the truck console, or the tackle box between games and it's ready the next time it comes out.

Not really. Beer pong and flip cup keep the cups moving constantly, racked in triangles or lined up down a table, and this is built for a drink that gets set down and returned to, not one that's picked up and slid every few seconds. It's better suited to the cup you're actually drinking from between rounds than the ones racked up for the game.
