Hi everyone, Just to let you know we have the brand new Xpro M50 in stock from Smoktech. Not much bigger than the Istick but can fire down to 0.2ohm resistance and up to 65w. Powered by a single 18650 battery that is then charged via mico usb when installed. We have had this on test all morning and are really, really impressed. Check out the full product description. http://www.cloudstix.com/smoktech-xpro-m50 We are pretty sure we are currently the cheapest in the UK for this at present. Any questions please do let us know.
