Very different products. Although this product is slightly expensive for what it is. It seems that this is more for supporting the campaign and a young company. It does seem to be something I'd find very useful in day to day life.

Do they reveal the expected price somewhere? The $25 kickstarter amount might not be the final cost in the long run.

I don't think you watched the video. This is a bottle opener. Whereas you're linking to a cable management device.

Epoxy or weld a binder clip to a cheap bottle opener. Done.

And a binder management device.
