If it really worked, I MIGHT be a sucker and buy it....the thing that got me looking at the demo was that the pins were all the same size. I have so many different kinds of pins with different size heads.....glass, plastic and metal and flat. I'd probably have to spend several days sorting out my pins before I was able to use it.
I can see where it might be useful for a dressmaker pinning a hem while the costomer stood on a platform: the dressmaker wouldn't have to look down to grab the pin.
Even though I LOVE gadgets, I will let this one pass!
