Up to you James. You can guess what I think, as these are 50p products (to the shops), so £4 is a lot of money.
Like I said, by the end of a year, you could spend £400 easy on throwaway tanks.
My first ever clearo (atomizer/CE4) was burnt out in about a day and a half. I didn't understand what to do with it really and just kept puffing away....
Did you see the pictures of the iSticks and Subtanks? They were next to each other for charging, so I unplugged them for a mod selfie.
