What is different from the old M?
I had an opportunity to try out the new 2018 M model Vapcap. Is it different than the original M? Yes, I think so, from a number of perspectives.
Asthetics always amounts to personal perspective, but I think I prefer the look of the new model and it offers a few clear performance advantages.
The stem sports vertical ribs to assist with twirling. They are placed perfectly to align where my fingers naturally grip the stem. Twirling is much easier over the smooth slippery polished finish of the original M.
The Dynavap logo is about half the size.
There is a deeper circumference groove aligned to the airport and a more pronounced cross hatch, so finding the airport is easier to find through touch.
The tip has been redesigned. It has a retro Jetsons appeal with its tapered fins and U shaped transition, similar to the 7 fin LE. I compared the heating and cooling speed with the previous M tip using the same cap. While the heating was identical, the new tip cools a few seconds faster.
The tip's exterior air channels have been split into two. Now this is where the magic is; this simple design adjustment provides much better airflow and the double channels look cool too! The entire tip redesign is an overall improvement in function and aesthetics.
I also found that the tip fits more snugly and secure in the stem. I switched it around with other stems and found it provided a tighter fit all around.
Overall, I feel that the 2018 M is an clear improvement over the previous model. As usual, George has made design changes that incrementally out performs that which came before.
