Note: This is the 6th duplicate (7th version) of my question (re. new
product/floss holder), and it is reposted because I have  new
questions without answers and  after the changes made in the web-page
in discussion, -- http://www.geocities.com/emailerss/ --
I would like to get an answer only from a researcher who is frequently
flossing -- using floss, two hands and no other help.

The web-page is showing instructions (mostly pictures) how to use a
patented dental floss holder (tensioner)and explanations .
This floss holder is good for about 250 all-teeth flossing sessions,
then it can break. I am asking answers to the following questions:
1. Is it clear from this web-page how to use this product, and how
many minutes have you (the researcher) spent on it?
2. Can a comment of at least one word be given by the Researcher to
the following chat  correspondance re. the product, and if yes then
what is it?

Question: I would probably not use this product myself. I have used
single-use floss holders similar in shape to this one, and I have
found that in using these I cannot achieve the desired angle between
floss and teeth-- usually I want the floss "bent" around my tooth more
than these devices allow. This situation may be different with your
device, though, due to the variable tension.

Obtaining bending angle of quarter of circle no problem. Floss between
prongs can run “parallel”toTeeth –betweenTeeth-“parallel”toTeeth for
most of the teeth. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<googel-1e

Q: Anyone who uses a disposable floss holder may be willing to use
this device. People with limited use of one hand would certainly
welcome this, assuming that the threading instructions don't require
two hands.
::::googel’s  answer: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

The floss is mounted using 2 hands before flossing.

Q: How long does the device take to actually thread with floss? 
::::googel’s answer: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
The  6-8 in. floss takes 15 – 60 seconds, 14-18 in. floss takes 10-25
seconds <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<googel-1e . .

Q: I like to occasionally switch the area of floss I'm flossing with,
especially if the floss is becoming thin or ragged at a particular
spot. Can this be done easily with the device?
::::googel’s answer: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 
The loop made from the 6-8 in. floss is great for this. It can be done
with one hand if one is willing to “bite” the floss between the prongs
and pulling/gliding loop aroung.

3. . Can you (the researcher) see any use of this product for
yourself?
