It'll be temp controlled but you hold a button like a manual and it turns on to your previously set temp instantly as soon as you press the button.
It'll still use draw sense... It'll heat up to set temp whenever you are holding the button and drawing at the same time (except first couple secs of button hold, when no draw is needed). It will also use draw sense to adjust heater temp based on draw speed (faster = hotter), so it will be much easier to learn because you can use any draw speed you want. Hopefully it can even be used while walking :)
The heater will be more powerful, but more important, the heater and herb chamber configuration are totally changed to better capture waste heat and to use more radiation heating (along with convection).
Also there is going to be a built in 4 or 5 chamber tray to allow rapid reload. Each chamber is about half the size of a fw4 chamber, but you can pack it in pretty tight so more like 3/4 the size. The reason for multiple smaller chambers is that you get more fresh, flavorful draws and a more consistent distribution of cannabinoids with each use (imagine if you use a large chamber and only take a couple draws, then an hour later take a couple more... the first session will give you more low boiling point compounds while the second will give you more high boiling point compounds, at least in theory) Smaller chambers also mean much better airflow. Even when packed tight you won't get clogging like on past fw models.
All these changes combined will mean it is much better for doing a really quick draw or two or microdosing while still being capable of larger or group session because of the quick reload tray.
