Comments on the Vaponic?

Thinking about purchasing one but one some opinions. I know there are better vapes out there but wouldn't mind this cheap one if it has some decent reviews. These are my questions 1.) How much odor (If possible, compare it to iolite, wispr, airizer, mflb, or puffit vaporizers) 2.) Vapor visibility (If possible, compare to same) 3.) How effective is it if I were to just use a bic lighter 4.) How much bud, on average, will get you high Thanks for the help
