Okay, the smart PCC is listed as coming soon on the
E-liquid Web Shop CN site. So, the factory is in production.
They also have the XL cart for the M40X series, which is listed as the same size as the current cart, but a different insert shape. Listed at .4ml instead of a regular cart at .25ml.
However, forum members have had very mixed reviews on ordering from this site. Payment is through Western Union only.
Eastmall has a PCC for $10 and a Long cartridge.
The PCC warns against overcharging and is in a case, instead of a pack.
Their Long cartridge is longer than a regular 40X series cartridge and is supposed to hold .5ml of fluid.
$50 minimum order and $15 shipping.
Everything I've seen from US suppliers is, not quite there yet or on its way from the factory.
The M702 series is only
cartridge compatible with the M40X. Everything else is different.
I haven't seen anything for a M40X super battery. As they last twice as long as the 501, getting out a super battery hasn't been that much of an issue.
