Cactuseven, i've been trying to find out some info on the Milano e-cig you bought. All I can see are pictures of the battery & cartridges. It looks like a super-mini of sorts - most likely a DSE 103. Can you tell us where you bought it from?
I've tried googling it & I can't see any sellers selling replacement atomiser for the Milano & though I may be wrong, it doesn't look like a 2 piece e-cig, so you will need replacement atomisers.
