this does work! but I don't enjoy the fragrance of it. We usually always have this in our car glove box, we like to go fishing and there are swarms of flies and mosquitos of all kinds so this definitely helps. I like the portability of it, not a gigantic bottle to lug around. OFF is a brand that knows the bug market

Product works great. We usually have bunch of these at the farm up North.

Mosquitoes love me, and nothing seems to completely keep them away, however this spray helps a lot to reduce number of bites

Purchased product as we have a lot of pesky flying objects in our backyard this year. One spray and they stay away. Should be third motto!

I'm always dealing with black flies, mosquitoes, horse flies, deer flies, ETC. in the summer time, so it's either cover up completely or use insect repellant on hand. I choose the latter! (Even though I'd like to try something more natural...)
I've used this a few times in the past month and it's kept the bugs away from me for the most part (the mosquitoes are more persistent than black flies, maybe the spray doesn't work as well on them?). The bottle says it repels for up to 8 hours, but I don't find that it lasts that long, more like 4 hours.
It's unscented, and I haven't noticed too much residue or 'greasiness' after applying it (there is a little bit, but not much and they have other formulas for that anyways).
The price is kind of high for these products, but they DO work.
