So you can convert the Mixx into a 21700 mod? That's a huge plus if so.

the 21700 battery sleeve and cap cost me £13

av just ordered another Mixx in frosted yellow (£34) uk vendor
I did see an all black version for £30 on another uk site
the blue one I posted a pic of above is machined anodised aluminium,
the frosted is plastic so should be a whole lot lighter

This is also worth considering at the right price
doesnae hit as well as the mixx and 18650 only
but small and compact wi the right tank on it
