Hi everyone I have been using the 801 atty from iken for like 2-3 weeks started up a new one couple days ago, I drip 8 drops everything was fine till last nite its hissing is that normal. I am new to atomizers too usually top with 3 drops or it starts to leak. Get a lot of flavor from them and they the best I have tried just want to know if thats normal? Also when u blow these out which end do you want to blow from.
