The 2019 "M" offers one of the best butane vapourisers on the market, no electronics just well engineered medical grade stainless steel.

Heating cap clicks at optimal temperature, clicks again when below temperature threshold. This helps prevent any damage that may occur due to overheating.

The new 2019 model adds tactile chamfers around airflow port for easy draw adjustment during use. 

Simple disassembly/self-service for cleaning.
