Title: A Bitter Wind Blows
Review: I've made several comments against bitterant on other air dusters and in the end I went with this one because there weren't any comments (at the time) stating whether or not it included it or not and nothing in the description at that time noting its presence either. Its no surprise now (as other reviewers have commented) that I got "bit." Yes the product contains bitterant, but not to a degree that I could detect from smell, though others may be more sensitive to its smell than myself. Aside from that it does do the job it is supposed to do, initially. The air pressure drops after a few sprays and it becomes all but ineffective. I ordered two packs (4 cans) and the result was always the same. I'd bought a different brand at Staples about a year ago, that really did the job down to the last spray, but of course they were out of it at the time. One could definitely do better than this.
