It depends if you are talking about the sole winning concept or the image that is shown on CMF

The original winning QDS design concept had two independent clamps and the instruction 'pull to adjust size

the winner

The concept has since changed to include an angled block which splays the wire outward, presumably to keep the tension in the loop.

CMF render

I think the original 'winning' concept was lacking proper functionality, and it is only by including the splaying block that it now has the ability to fill out the sleeve.

It seems to me that the thing that makes it clever is that block. Now if only somebody had come up with that idea!!

of course the CMF

Yes the CMF version looks useful - I'm not saying I would use it endlessly, but it looks like it would be worth a try and who knows?

My two-cents on this product... When ironing, I hate running into bumps and seams. I like my pants/shirts to have a sharp crease. With the current design, I have a hard time believe that it will be more helpful than cumbersome.
