Assuming you are referring to a DSE801 atomizer. All are not the same. Most places sell the High Bridge Atomizer.
Myvaporstore.com in sells the Joye302 Atomizer it is 100% compatible with the DSE-801 battery and carts but it doesn't intrude deeply into the cartridge like the High Bridge do.
Result Wicking is tremendous and you get a more even vape.
So far this is my favorite DSE801 Atomizer a close 2nd is the Bestecig.com BE112 but you have to order this atomizer from China although they do have a new store that opened to carry there stuff in the U.S.Forum members have raved about the atomizer but many say the bestecig
batteries are too sensitive. I found the Be-112 to have a atomizer that is shaped like the High bridge but it didn't penetrate the foam. The Joye302 on the other hand is shaped like an arc.
