I honestly know f**k all about them mate, will take a look at the ones you posted when I get a chance.
Bought it Monday and I had it I near bounced it off the wall after half an hour, wouldn't work and for the life of me I couldn't understand why, so brought it back and there was a dud coil in it ffs.
Actually had to buy a packet of smokes it was getting on my tits that much
It's always a problem with those cheap all in one jobs.
Some are OK, from what I've heard, but some are crap.
I experimented quite a lot when I first started vaping, but quickly settled on box mods and stock coil tanks.
Easy peasy that way.
Only problem is for box mods you need batteries (mostly) and a charger.
With juice I get 100ml mix kits from a place called Justaddnic and it works out less than 2 quid for 10ml
Lots of different products and advice out there if you carry on with it.
I found it was the only thing kept me off the fags, and I'm slowly bringing down the nicotine strength in my juice now so I can bin vaping as well.
