"I did not intend to hit a nerve. And I agree that any time spend in ill fitting shoes is causing harm. For decades we have been sold on the need for cushioning, support, orthotics, etc. when what we really need are strong feet that cushion and support themselves. And we can all do that for free. As for who I am, a former recreational long-distance runner that has spent years rehabilitating his feet from the deformations caused by conventional footwear."

"Continues to drive me crazy that conventional footwear companies can put out this garbage without any concern for what it's doing to people's feet, and bodies in general. Sure, let's strap 4 sponges to each foot and run 26 miles. What could go wrong? Forget the waste of a disposable running shoe, not even getting into that. "

"I've always found great joy in the small discoveries lurking within disorganized junk drawers (which seems redundant, now that I see it typed out). "

"Please, ramble on. I enjoyed reading this comment. "

"The video shows it cleaning clean bathrooms. How utterly useless. Put that thing in a dive bar and let's see how it does. "

"What could go right?"

"It's great that someone is looking at this product in a new way. And the idea of shielding yourself from fire as you move to an exit is brilliant. But everyone knows the form of a fire extinguisher. In a real emergency someone may run right past this not realizing what it is. How do you re-educate people on such a massive scale to recognize alternative forms? And is the common fire extinguisher really that much of an eye sore? We have white ones at home that I peeled the stickers off of and applied my own stickers. Now they're art!"

"This is my biggest gripe with the design. If you look at where the trigger is you can see that it only works when held in the left hand. If you are missing that hand/arm, or have limited mobility, it's useless."

"Ironically, wouldn't your arm fall asleep before you do?"

"This video made me laugh until I was in tears. Even at night, I was chuckling to myself just thinking about it. Watch his legs come out of the chute - he's in a sitting position. And the sound of him coming down the chute once he cuts loose? It's comedic genius. Thanks for sharing!"

"Where does it go when you're not using it? Just one more thing to try and fit under the seat in front of you."
