I probably hunt the same swamps as Splittine and I completely agree.
I'm not sure about repeling chiggers and ticks,my "guess" would be probably not. However the unit is kick butt on skeeters,no see-ums,and biteing flies.
The little butane cells also can be bought at your local drug store as the same thing is used in a cordless hair dryer for women. Allot cheeper also.
The Therma-Cell goes with me into a shooting house or up on a ladder stand during the summer,while hog hunting. Works like a champ.
You WILL fight....like you train !
