I purchased my XS more than two years ago, and it served me incredibly well all this time. It was the first vape I ever bought, and given the positive experiences I had, I’m happy to upgrade it to the newest model.
-portability and discreet appearance
-high quality and consistency of burning
-fast heat-up time
Things to be further improved on:
-mouthpiece design (the magnetic one on the X sounds very exciting)
-heat dissipation, especially around upper part of device and glass of mouthpiece
Overall, though, would very highly recommend - it is a great little device than can be carried easily and be used everywhere due to its conveniently simple mechanism. Would buy again.
