What a good choice! I have had a VTR for a couple months now and i love it. My settings are usually (P) whatever that stands for, between 7 and 8, and the (U) between 4.5 and 5. I found that it works really well on those settings. It took a little time to get use to though, learning how to draw from it. After a while of using it, I was able to gauge how long to push the button by the heat of the vapor, and also i was able to hear it heat up as well. Overall, im really happy with the VTR.
