Well, I've had my "M" for a few days now and I really like it. It's a great little vape, especially considering the price. I think I still prefer my Ti woody for its heat transfer and airflow characteristics, but the M is definitely a nice addition to my vape collection.
Here's a pic of the new M next to my old Ti woody:
There's definitely a noticeable difference between the two, performance wise. The SS tip has different thermal properties than the Ti tip. The SS retains and conducts heat more easily than the Ti. The M seems to vape the load slower and more evenly, and the Ti tip seems to extract faster.
The airflow is different with the M: with the carb open it feels less restricted than the woody, and with the carb closed it feels more restricted. My guess is it has something to do with the lack of notches on the end of the tip:
Because of this, the M requires a slightly different technique. I find myself doing more mouth pulls with the carb closed, then "clearing it" by opening the carb; whereas with the woody I'll usually hit it with the carb open.
I've also been experimenting with changing the airflow in the M by pushing the condenser farther into the tip. Here's a pic of the mouthpiece end, you can see how far I've pushed the condenser in:
This definitely adds a little bit of restriction to the airflow. Makes open-carb hits a little denser. Not sure yet if I like it more this way or not, I still usually use it with normal condenser placement.
Oh, and there's this:
I call it the Ti M-XLS.
I put the Ti tip from my woody on the M body, and added the XL condenser and spinning mouthpiece. Fun to mess around with, though I've since reassembled the two vapes with their correct parts.
So yeah, to sum it up, I've been having a blast testing out my new M!
Stay vaped!
