TLDR: easy to use, very effective, fantastic price point.
I've used multiple different brands/styles of vape pens/sticks with CBD oils. Firstly, the CBD oil products here are fantastic, with great flavor options and effective doses of the CBD. They're also more affordable than comparable sites that sell similar items. I recently purchased the PREMIUM CBD STARTER VAPE KIT. This is hands down the best and most effective vape pen/stick I've ever used. None of the "popping" of hot oil on your lips; the vapor itself stays cool, so each hit is smooth as hell; the battery charges rather quickly; the cost is quite affordable, especially for the quality of the vape pen/stick itself.
