I got my first X Max v2 back in 2015 and I still use it today!! This is one of the great things about a vape with a replaceable battery... longevity! The new one I received in the mail is even nicer as it has a slightly updated control and new glass accessories (extra). The updated controls are simple... click three times to turn on and hold button for two seconds to advance temperature through the five preset levels. This is a conduction vaporizer with a fairly large ceramic chamber. Flavour on the x-max is great likely due to the fact it makes use of an isolated air intake with lots of venting.
