Having a lot of camping background, and being in the outdoors in the summertime, I have gone through a number of types of Bug Repellent.I first saw this at a friends cookout in July. I was completely shocked and sold on it in a matter of seconds. I have never seen a mosquito fly toward an arm, stop, and turn around. This is exactly what happened a number of times at the cookout to my friend, and myself as well.I immediately ordered two cans of this spray as soon as I got home. This is something that I was not going to let get discontinued on me, like most great products do.It has Deet, and if you have an allergy to Deet this is not for you. For everyone else, you will not find anything better.It has a bug spray smell, so that is the only trade-off I can think of.I have never sprayed this on jackets or nylon fabrics, and probably would not recommend doing so.I hope this helps, and enjoy a bug bite-free summer.
