Works brilliantly but the mouth hole is sharp and uncomfortable
This thing works absolutely as advertised and if you do it correctly (i.e. make sure you get all smoke in the lungs in one go with none escaping) and you make sure you have a good mouth seal around the hole, and you make sure to replace the caps quickly, then there is absolutely no smell. The only reason I'm giving it 4 points instead of 5 is that the rim of the hole is quite roughly cut plastic and is consequently a little sharp and irritating. I'm sure you've probably experienced sharp edges of plastic in cheap toys, etc. Not the most tactile experience. Not to the point where you'd stop using it, but it is the one bummer aspect of the product and so deserves a little slap, especially as it wouldn't be that hard for them to add one more little step to the manufacturing process and smooth the mouth end down.
