I want to say something about the Dabbler. I am liking it. I love all of the pens, but the fact is, when things get hot, cartridges can leak. Carts when in hot climate are best kept upright. To that end I invented a calf pocket, made of my wife's blue jeans butt pocket, and a garter that goes around my calf... That part of my anatomy is always perpendicular to the ground, so I never spill. I have enjoyed the ease of carrying my Dabbler, in it's ultra flat and small case, and just bringing along a small container of wax. I still love my other vape pens... each has a feature or two I love... The Dabbler is great for traveling when it is hot, and I am afraid of laying my pens down.
