I haven't tried this product, but the short pad life and @$$ of the pads puts me off.

I have about 10 kinds of bug repellents for a "Bug Juice Bar" down at the Harold Hang this weekend in Mass.
People will be able to check out all the popular options from DEET and Picariden to the new DoD mil-spec IR3535, plus many varieties of "natural oil" choices.
I'll put up a link to my blog post on folks impressions once we're done.
