The T° on the device is only for reference, with convection heating the T° in the chamber may be influenced a lot by the drawing style, loading style, ambient T°, herb's moisture content and hit's length. In short, with convection, the more you draw on the device the more vapor you get while with conduction, you are "emptying" the vapor build between hits. You may be able to get the vapor you want at 175°C only by modifying your draw in order to add more fresh air (pull faster), by loading less in the chamber (my typical load is 0.10-0.12gr) and by taking care your weed isn't too much dry (some moisture helps to get less dense clouds)
Yes it is... we did it cause customers complained the device need too long draws to deliver.
I think you are enjoying low temp though...
It's normal the device keep the heater on with the T° set at 130°C between On-demands button push, only by the time the timer isn't over. We did it in order to fasten vapor production (less long hits) but also in order to save some battery life. It was already mentionned the device to produce small clouds in On-demands mode only by drawing on the device (without to push the button)... and since you seems to enjoy it at 130°C... On-demand mode seems useless for you!
I don't think it's a bad one, it looks like you are a low temp vaper, although most persons, when quitting combustion, want to get a device able to produce dense enough clouds to mimic combustion hits. Our devices are designed for such persons... but we are pleased to notice many "connoisseurs" here seems to dig the Xmax V3Pro too...
I'm so glad you finally got the hang out of your V3Pro, your other device is conduction based and designed to deliver clouds all over the entire session. The V3Pro is convection and it's designed to vape a full chamber (0.10-0.12gr) in 3-6hits (it depends a few factors: hit's size, thc content, T° settings and with or without water cooling).
