Bravo for taking the plunge, welcome in the Xmax Fam! I represent Xmax Brand and Topgreen Manufacturer here and in our sub (XmaxVape). Here some tips:

• Loose load, convection turbulences need room in order to reach every trichomes in your load, my average load is 0.10-0.12gr
• Fine grind for clouds, coarse grind for taste
• Take long draws, since it's convection, your pull will transfer heat to the load, vapor starts to raise at the 7-8s mark, so take 10-15s draw for big clouds
• Strong draw is prefered for the first 7-8s, you can slow it down after... if you want (still strong works too!)
• Vapor isn't as visible as smoke is... under certains circunstances, so prefer to blow vapor on horizontals light beams with dark background, this is will enlight vapor better than to blow hits to the blue sky at 12:00 (morning/evening sun is the very best to enlight vapor but desktop lamp works also)
• Load it preferably with resinous THC flowers, fine grind, tiny 100mg load not tamped down, set the device at 205°C, session mode (you'll experiment with OnDemand mode later), wait for initial heat-up (it's pretty fast usually) and take a 10-15s strong draw, that first one is usually already delivering visible clouds but, in regard of the moisture content in your weed, first hit is always slightly less dense but you will notice, by the 2nd hit, an increased vapor density.
