The Xros lineup is the best series that Vaporesso has produced. The Vaporesso Xros 3 is the vaporizer I have been carrying around for the last week. So far, it had been the best pod system I have tried. It is mainly a MTL/DL system, although I have been able to use it for RDL vaping by using the button. It maintains a smooth hit, and it has amazing flavor with both free base and salt liquid. With salt liquid, I noticed that it has a very noticeable “head high” effect, if thats what you’re after. Overall, the build quality isn’t amazing, but from what I can tell the focus is in the pod, not the device. I’ve tried all the pods, and the 1.0 ohm pod seems to have the strongest flavor. Definitely a device I will keep with me. There are some issues while using the website, but Vaporesso devices are common enough to find at any vaporizer shop in the US. The website was cheaper than in person at MSRP, but it wasn’t a big difference. At $10 a pod, its a bit steep, but the quality definitely shows.
