"Not too far from a shooting stick (but the tripod base would be more stable). I would think sitting on one for any period of time would be uncomfortable, but they do nest up tightly, so I guess they're more for convenience of the venue than the sitters."

"They look great, but the ergonomics seem suspect - at least they have some lever versions, but the plain ones would be hard to pull a door closed with - one-way knob...."

"Oho, it's a gimlet plus, that looks very useful."

"A very strong Close Encounters vibe, but I can see it would be much better than floodlights / flashlights / headlamps in the field."

"I want to believe? For the US, I wonder if it wouldn't be classed as a motorcycle (and thus require wearing a helmet...) and I wouldn't want to imagine what getting hit by a Rivian or other giant truck would do to the driver..."

"Within reason - imagine whittling away enough wood to only leave a long piece of graphite, like a few cm long - it'd break without the wood to support it."

"Hmm, non-replaceable flash memory doesn't sound like a great idea, even with a good controller I would expect wear to be an issue over time."

"For me it evokes the trend of slapping giant touchscreen head units into cars, instead of a simple connection to a phone that can replaced / upgraded. Yes it's "ugly" to mount just the things that you want on your bars (I have a bell, light, and GoPro, but I am commuting every day...) but it's also modular and you can easily move some or all of what's on your bars to other bikes."

"Hmm, seems like e-waste in the making, the hell of consumer-grade routers is that they only get support (bugfixes, primarily) for a couple of years and then they're just a sad security nightmare. I don't doubt Korea Telecom will exist in 5yr, but will they still be keeping these alive?"

"It's creative for sure, though rounded carbon-fiber 'knuckles' don't seem like they'd do a lot of damage (they should be plenty strong enough to carry a bag of groceries, at least)."

"Looks like some of the walls are hollow, I assume they run conduit and pex in there?"

"Doesn't look technically too complex, quadcopters get their stability from spinning two rotors one direction, and the other two the opposite direction (diagonally), this design spins the upper rotor the opposite direction from the lower (easy to see in the dumping-water video clip) instead. The only not-off-the-shelf piece of engineering I see is the central shaft that couples  the two props plus motors to let the spin while staying connected."
