Atomizers … I suggest always keeping 2-3 on you at all times, this allows time to get replacements once one goes out. Whether I just have good luck or not, but my mini atomizer (that I use 16+ hours per day) is still going after 2+ months of use. In the beginning, you will probably go through 2-3 right off the bat. Once you get the hang of things, and you learn to take care of and see warning signs, you can save them many times, thus prolonging the life.
