So I've had my Pax for a few months, and it's fucking awesome. However, something I've started to notice is that whenever I clean my vape, it hits for only about 15 hits, but when after I use it 10 times it starts to last almost twice as long with a lot more vapor. This really doesn't make sense, but it's been happening for a while now. Has anyone else noticed this? Sent from my iPhone using Grasscity Forum
