I treated the eVic exactly like all my other mods. I put it on my heavy computer desk standing upright while I was on the computer actually right next to my Provari. What I didn't account for is that the eVic is taller, lighter and with a full carto tank tends to be quite top heavy. The Provari on the other hand is extremely solid with a lower center of gravity. So I get up and slightly bump the desk which happens all the time, Provari barely moves and eVic goes flying off the counter. Mind you this is about an hour after I received it new. I pick it up not even thinking there would be a problem because it was such a light fall onto carpet. Low and behold the little navigator ring must have gotten crimped slightly and it started sticking to either side when selecting stuff. I got it warranty replaced and sold it immediately after receiving the replacement. After putting it up in the classifieds I could only get $65 for it with extra shorty 18350 tubes and I was still glad to get rid of it at almost half what I paid for it. Not only is it cheaply made with inferior materials but it also becomes less accurate the higher the voltage and the less of a charge you have.
I don't think there's anything I could learn in a class from eVic owners except how to deal with a horribly made cheap Chinese mod.
