It's always a good idea to have a backup DSE901 atomizer. Atomizers, after all, are the most unpredictable part of an electric cig and, based upon how much they are used and/or abused, could last for just weeks or for a couple of months.
This DSE901 atomizer is the same as the ones that come with the DSE901 e cig starter kits sold on this website.
(Price listed is per atomizer)
