Every question, answered.

Yes — a tallboy shares the same base width as a standard can, just with more height riding on top. The fins grip the bottom inch the same either way, so the extra height doesn't change what's holding it up.

Those run narrower than a standard can, closer to 2 to 2.25 inches, and they still settle in. The fit spec is 2 to 3 inches across, and a slim or sleek can sits comfortably inside that range.

It can — a sleeve adds bulk the bare can doesn't have, so the fit gets tighter with it on. If it feels snug, pull the sleeve off; the base grips the bare can fine either way.

That's the point of the wide base — it spreads the can's weight instead of letting a narrow footprint sink in or lean over, on turf, on sand, on a boat gunwale, or on a concrete floor alike.

No. Nothing drills, stakes, or clips to anything. It sits on top of whatever surface is in front of it and moves to the next one in a second.

No — that's the one honest exception on the fit list. The base fits, but a mug with a handle doesn't seat, because the handle lands exactly where a fin needs to close. Handle-less mugs and camp cups within the base range are fine.

Movement is the actual design brief. The base flexes with a wake or a vibrating liner and settles the can back level. It resists tipping — a direct hard kick still wins, same as anything sitting loose — but the ordinary bumps of a day outside are exactly what it's built to shrug off.

Rinse it or run it through the dishwasher. It's one piece of flexible material with nothing to unclip or take apart.

Yes — AriZona's 23 oz can uses the same roughly 2.6-inch industry-standard can body as a standard or tallboy can, just stretched taller, about 8.125 inches, to hold the extra volume. The base width that actually needs gripping doesn't change, so the fins hold it the way they hold any standard-width can.

A standard 12 oz longneck beer bottle runs about 2.4 inches across at its base — inside the fit range — so it settles in the same way a can does. It isn't can-specific; any round base in range works. Cans get the focus because they're the one format with no lid to catch a mistake.

Rinse it off. It's one piece of flexible molded material, not a sewn fabric sleeve, so there's no lining for grit to work into the way it can with a foam or neoprene koozie. A quick rinse or a run through the dishwasher gets it back to clean.

No — that's a different job. A koozie's real function, by its own advocates' account, is blocking condensation more than insulating, and this doesn't touch temperature at all; it holds the can upright. Plenty of people use both together — koozie for the sweat and the chill, this underneath it for the tip.

That depends on how many hands are usually holding a can. A boat with three people aboard needs three, since the one factory-installed holder only covers one spot. A tailgate crew often keeps one per chair. There's no fixed number — it goes back in the cooler bag between uses, so an extra one costs nothing to carry along.

It tends to land well because it doesn't require guessing anything specific about them — not a chair brand, not a boat model, not even which size can they usually drink. The fins adjust to whatever they actually set into it.

An ordinary bump — a dog's tail, a kid running past, a boot near a camp chair leg — is exactly the kind of hit the flexible base and fins are built to absorb and settle back from. It resists tipping through that kind of everyday contact; a hard, direct kick still wins, same as anything sitting unattached on the ground.

A stake only works where you can drive it into soil, turf, or sand soft enough to take it — it does nothing on a tailgate bed, a boat gunwale, a dock, or a garage floor. This doesn't stake into anything; it sits on top of whichever surface is actually there, so it covers the hard and moving surfaces a stake holder can't reach at all.

It's molded as one solid piece — no spring, no hinge, no separate parts that can loosen — so there's nothing mechanical inside it to wear out. The flex comes from the material itself, not a moving part that fatigues over time.
