Considering the Crafty - Are there still issues?
I've used the mv1 for a few months now. The quality is good, although the stealth chips off easily. It's very hot and the draw is good. The app is shocking though, I couldn't get it to work.
I like my mv1, I think it's more efficient and gives you more vapour than my arizer extreme q does as well.
I've not used the crafty but I did consider the mighty. I got the ghost after reading a lot of reviews.
Essentially I would have to say the MV1 is an excellent addition to a collection of smoking apparatus for anyone.
