"Agreed - the inner material of the 'cup' seems to be wood, not a great material for suction. It looks like a spacer/washer to stop the thin metal base being deformed by the screws used to fix it to whatever surface it goes on... I'm unconvinced of the accuracy of most of the speculative waffle in the video. I can't see much compelling evidence of its 'travel' credentials."

"There's nothing new in these; the same idea was marketed in the 1970s as the 'Tufspin'https://backcataloguedotblog.wordpress.com/2017/07/20/tufspin-swivel-boots-theyre-revolutionary/They were a rarely-seen marketing flash in the pan back then, and given the revolving-door, new ideas marketing treadmill of giant sportswear companies and their shiny, 'visible technology', 'give us your money' marketing strategies I don't suppose these will last long either. Shame, as it seems like a valid idea to cut down on twisting injuries - especially on artificial turf with its grippier nature?"

"This is a version of an existing product - 'Isosketch' that's been around in the UK for several years now. https://www.youtube.com/watch?v=uyhcYLbb52cI fI were the Isosketch creator I'd be well annoyed at this. But I guess it's different enough not to step on any patent or copyright toes? I use it in class, for beginner drawing lessons, and I agree with the post - like all things I think it's better to develop the skills manually  and than if you choose to use a shortcut tool, fine. But as I tell my kids, if they draw only using the Isosketch then they'll always do work that looks like that and is limited in scope. The constraints of the education system here means that actual skills are undervalued; and the opportunities to teach good graphical skills doesn't fit easily into the narrow (easily examined) curriculum."

"Call me a pedant, but... The headline would read better as 'An Industrial Designer's Take On...', making it obvious that 'designer's' is - correctly - apostrophized, singular. It looks like a misplaced apostrophe for a plural '[Some] Designers Take on...'Nitpicking over. Back to the article!"

"Nice looking and useful in a niche way, but - £88 GBP on Amazon. That's a definite "No.""
