1) About two minutes spent looking at the page. I believe that if I
had the product and the directions, I would be able to use it as
described, but it is not exactly 100% clear. On initial viewing of the
page, I read all the text except the bottom half of the bottom-right
text (starting with "Loop&knot can be glided".)
My significant other said "That looks terrifying!" upon being shown
the page, and I have to agree. I think that at least part of the
problem is the sheer number of units on the page (I count 18, and
they're not simple-looking devices!)
I think that one or two illustrated close-up for each method, clearly
showing how the floss is threaded at the end and possibly an "active"
intermediate step, would be clearer and less intimidating.
2) I would try it out if offered for free (I tend to enjoy playing
with new products), but I suspect that I would not end up using it on
a regular basis due to its complexity and the fact that I don't have
trouble flossing by hand.
3) Primarily due to the apparent complexity and preparation time, I
cannot think of anyone who I believe would be interested in purchasing
such a device.
I think that you would need to stress the advantages over other
similar products -- namely the ability to, for example, store such a
device in your wallet.
How it is used also seems clearer after thinking for a minute about
how it works; which is, sadly, more thinking than I'll bet most
potential customers (including myself) would do. If I'm correct, the
floss is tensioned by your hand squeezing on the notched "leg", which
you basically just wrap the floss around. Knowing this makes me a
little more interested in the product (though I still wouldn't buy it
out of the blue, I might be more interested in trying a free sample),
as it doesn't seem that hard to just wrap the floss and insert it in
