Wow, those are super funky. Cool to see 3D printing coming up in the vape industry.
I personally use the Von Erl pods and I was shocked at how much I liked them. Norm and I got them as a gift when we visited Michael Guasch at Molecule Labs.
At first I was skeptical of them because I (mistakenly) bought some Vuse ecigs one (drunken) night and they were just awful. I wrote off pod systems since then.
Now, with the Von Erls, my wife and I vape on them quite a bit because they have great flavors and the experience is fantastic. Good pull, plentiful clouds. They are a great starter kit, but also a great "utility" vape for people that want a portable and flavorful vape pen.
Don't discount these in your shop. I haven't tried the Juul, but I would recommend the Von Erls in a second to anyone looking for a pod system.
