The 401 atomisers I have had since early Feb to Late Jan are still goin strong. I have only had 1 die on me from my first batch. I soak them in iso alchocol every night and rotate them. They produce a ton of vapor. I have had some new attys sent to me but some dont work right but I have plenty more that are still unopened. I will stay true to my m401, I tried just one other ecig before and have read a ton of reviews on others but I do not have the money or the patience to switch anytime soon. The 401 is AWESOME
