The AiroPro works by using a CCELL cartridge that's not threaded. As opposed to threading, it has a straight magnetic connector. The magnetic connection had to be adjusted once in a while by popping the atomizer again in and urgent it. We have been sorry for just about any inconvenience; https://johnnytrtay.affiliatblogger.com/85440408/buy-airo-vape-cartridge-with-paypal-can-be-fun-for-anyone
