Since you skimped on the vape, you might have to discover some sort of trick that gets it to work with acceptable results. Maybe the temp isn't correct on it and you are scorching the weed instead of vaping it, that or it is actually too low and you aren't fully vaping it. Hard to say cause I've never used a vape before so I wouldn't know what would cause them to not work. I would think it would be pretty hard to screw up something like making a vape though, unless you really didn't know what you were doing or used very crappy parts.
