don't even consider throwing any amount away on a hot plate vape. you'd be better off trying to use your stove top as a vape, seriously. just save up your money and be ready to spend $150 - $350US and lots of research to see which method you'd prefer. I gotta say, after getting a nicer one, the the reliability and super-low maintenance with great functionality make it well worth it. I barely use 1/3 (if that) the the herb I used to and get blasted.
