The problum is the batterys,the batterys do not last long before needing to be recharged,so as the battery is loseing its charge you get low voltage and low voltage is bad for any electronic device. So if you have to change your battery on your atomiser 5 times a day then you get low voltage 5 times a day, and this is why you are needing to clean your atomisers. I very rairely have to clean mine because, the batterys are 3.7 volt,160mah, I boosted mine to 3.7 volt at 1800 mah. Whow what a differance in the performance. So you do the math my 510 stays charged 11.25 times the stock battery. Soooo if you have to charge 5 times a day ( or change your battery ) I change mine every 2 days!

My next step up is to go to 3.7 volt at 2700mah!

Thats over 3 days before chargeing or changing a battery!
