This is a question probably best answered by those who aren't 100% newbies, but I'm wondering how many of you actually test new atomizers when you get them, especially when you get several at once. It's easy (and probably a good idea) to give new batteries a full charge and test them, but if you get 10 new attys at once, do you go through the motions of making sure they work or do you just chance that they will work sometime down the road? TIA
