Mistakes are life's best lessons.
Unscrewing the wrong part and having juice leak all over my vv 3.
Laying my unit down only to end up with juice on my tongue.
Buying too many plastic iclear tanks with wicks, because they're cheap. No longer care for long wicks now as they get in the way for me.
Over tightening parts.
Buying things I may never use.
All the same here
Starting out with Blu e-cigs. If I had read more on ECF and done my research, I think I might have started with something better.
Another: buying too much stuff - 808's, 306's, spinners, vv gripper, mvp, vamo... I could go on with cartos, clearos, BDC clearos, .. I think you get the picture. But so many choices, and I'm not sure I would have appreciated the things I like now had I not bought all this stuff.
Stockpiling coils that I later found were simple to rebuild and better after rebuiding.
I did a lot of research before i bought my mod so i did not have any problems there, now i make my first DIY juice and i did not buy sweetener for the green apple flavoring that i bought =( now im stuck vaping this bitter juice until my sweetener gets ship on monday
