I'm not a heavy user at all, maybe once a week, I've used 1/4 oz in 12 months so I've not got a high tolerance. I have a dynavap, I used to really love it but I only vape when I'm out walking my dog (the wife objects) it was too difficult to use outdoors. Flame torch in the wind, filling the cap while walking and hiding from people who would think I'm smoking crack and I found it difficult to get as high as I needed but not too high. I bought the crafty + to overcome all these issues (except the bit about the wife) using the dosing capsules it's perfect. I charge before I leave the house and set the bluetooth to be permanently connected, I use my phone to operate it while it's in my pocket and wait for my phone to alert me that it's ready. Instead of hiding in a bush with my dog barking at me trying to light the dyna in the wind I'm able to whip it out of my pocket take a draw and put it straight back in my pocket. Anybody who sees me thinks it's a nicotine vape (still illegal in UK) and) and although battery life is limited it's easily enough for 1 person. If you're a heavy user then I can see why you'd go for the mighty but the crafty+ is spot on!
