Easy to use,
Great product will buy it again!
For a novice vape user, the spring clip installation wasnt very difficult. Works great
Watched videos, they were helpful. I know AVS is working on a better clips, they should provide more extra clips with purchase of M22. I used my extras for practice, basically. Fine product in the M22 ESCC, bur like the title of this review says Needs Improvement, very fine tuning. Does not effect my high regard for the M22, my newly prefered Go To
