I've been using the Picaridin for over two years now and like it. It does not seem to be as uncomfortable to the skin as DEET and, most importantly, it will not dissolve plastic. If you are not aware of this very nasty little habit of DEET, just use your cell phone after putting it on and you'll find out the hard way. My experience was in 1994. Fortunately, replacement cell phone parts were not such an oddity as they are today.
