I bought the OFF Clip-On because I had a coupon, not really expecting it to work.  I don't really care for all the oily sprays and wipe-ons so was quite relieved the first time I used it.  We were camping and had to leave the door of the motorhome open and I was thrilled to be able to sleep with out being eaten alive.  I am allergic to insect bites and hate getting them as they swell up and take weeks to go away.  A month later I forgot to use the OFF Clip-On and got all bitten.  I won't make that mistake again. 

What I like most about the OFF Clip-On is the light scent and the little fan...
