These little vape pens are so convenient... I hardly ever leave home without one. It's so easy to take a few clandestine hits almost anywhere! Hardly ever smoke flower anywhere but home.
Back in the day to vape you basically hate to take knife hits. Which were so damn sketchy I tried it once and was like, nope not my scene.
Vape pens are super effective but... they don't deliver the thrill of a big rip from a bong or pipe and the long slow exhalation. Sometimes you don't know if the pen is working or not.
wax is nice in mod box type setups too. I have a vaporizer from a place called Vaca Vapes with coils that take big ol globbies if you want - $50-70 altogether and you get messed up since it's not 3-4W in a pen. I pay $35 or less for a gram of decent stuff. I still buy and use flower, but it's such a tremendous pain in the butt compared to snappin of a little piece of Blue Dream and hitting a button.
#4 actually quality glass & steel cartidges are refillable, including the Nectar Craft one mentioned. Refills are available in many varieties. But, yes, the overall trend of "disposable" in vape & e-cigarettes is troubling
I know Heylo makes plungers that can be used to refill their raw extract vape carts. They have a number of tasty products. http://heylocannabis.com/strains
