Pros small, portable, easy to use and best of all MINIMAL SMELL. Like almost none. Cons high (ha) maintenance. Replacement mouthpieces are available. I'm looking to replace mine after about 30 days of use. If you clean after every 2nd or 3rd use then you'll get more time. Luckily the replacements are cheap (3-5 dollars on gpro's site, not sure about here) The temps are 3 presets so that might be a turn off for some, but didn't bother me as I am a beginner in the world of vaping. The benefits far outweigh the minor inconveniences. Great product, would consider purchasing a second (different) product from the same company.
Perfectly fine, does the job adequately! Bought mine for a bargain frok the site, happy with the purchase.
