You can even rebuild some of the Vision Egos now can`t you, not to mention the Vivi Novas...and the replica
high end rebuildables aren`t all that expensive now in certain places.
If you can get into rebuilding your own it`s going to cost pence rather than "pounds" to renew each time, but cartos are only about a pound each, as another option....
nothing lasts forever though and it`s down to the user to decide which is a good compromise between cost & mental torture (I can`t be doing with the rebuilding stuff)
If you can & want to do it, rebuilding will be the cheapest option over the long run.
I have rewicked a Nova and it was easy...if I`m saying that then it must be because I`ve got no patience whatsoever for fiddling about with things.
On the other hand I had an RTA & an RDA and they drove me round the twist.....yet some people don`t seem to mind.

Aside from all that....I notice that all 4 clearomisers died today, was that literally all at the same time ?
I`m wondering if there`s a problem with the battery....as in, the battery killed them due to a fault..or there`s a problem with that particular battery...have you got a different battery to test with ?
Just trying to work out what`s actually happened.
