Mark,
I don't know about these, I have seen good ones and usless ones. Gauze is often a real test for scissors. Many good ones are not tight enough to cut it. I prefer a bandage scissor in my FAK like these I bought from Survival Resources:
http://www.survivalresources.com/store/product.php?productid=17733&page=1They also have folding scissors, but they are even more expensive (5.95 vs 2.95 vs 1.00 for the ones you are looking at). Since they seem to have a good return policy, it might be worth trying.
No association except as a happy customer.
Respectfully,
Jerry
