Cheers everyone for your tips, especially the vivi nova part.
I have put one on the battery today and it works seriously well. Far better than the ego c tank system. That thing seemed to leak a bit where the head needle pops into the tank and is a pain in the a55 if you ask me.
I can see that the vivi is far better and I wish I came across this site before I forked out for the ego c starter kit!!!! I have ended up with two pretty expensive batteries and a load of left over bits.
At the moment I have the 2.4ome head in it as that was there to start with and it is working well I would say, really well compared with the ego. Should I want to try the 2.8ome head could you recommend the BEST batteries to buy in the future.
I am also thinking it may be a pretty easy job to make a cheaper battery pack for it??????? A battery, switch and the right thread and connection fitting???????????
Thanks again, Steve
