Yeah, We all have to remember that atomizers are not meant to last months. Yes, sometimes you get one or a few to last way way longer then ya thought...but you will find many that were made poorly, the air pull on many of them is different even though its the same type of atty.
I used to try to make a atty last long, but now, instead of putting myself through agony, I'll toss it if it isnt performing well. I used to try everything to bring it back, etc etc.
The last year almost I have stocked at any givin time 50-60 attys....A bunch of 801 type, 901 type, 510 type, iatty type, etcetc.... SO as soon as one dips in performance I watch carefully, and when it hits a certain point, I just toss it.....If I get 2 weeks to 20 days, I am happy. Sometimes it happens, Sometimes it doesnt. It is what it is...lol
