I just ordered a couple of LR 306 attys. So excited to try them. That being said, I typically only use an atomizer on a PV until it's time for a battery charge (about 1 day for a 1000 mah) and then it goes in the bowl for cleaning day. So, I clean them pretty much after only one day of use. Is that bad for it? I have to say that I do get frustrated with having to prime a clean atty every day......seems like just when it gets broken in and working like a dream, I'm tossing it in the laundry! How many days do you use one before changing?
