I am a big fan of the product. If you use all of the correct pieces(recommend buying the separate glass pieces), you can get an actual pretty good vape. Use without the ceramic screen and the glass insert it is pretty tough to avoid non-stealthy combustion because of direct contact with the heating element. Overall, I couldn't be happier with the design and simple functionality for $10!!... and it will only get better! It's def going to be a good thing to be a part of MCIG long. IMO
