I have 2 Flowermate both are really odor free. Sure there is some. But I'm very very pleased with the low low level. Also have x maxx starry. 10 times the smell of Flowermate
But still quite acceptable.
If you vape cannabis regularly, your nose has become partially "blind" to the odors. Never trust your own nose, always ask a friend who doesn't smoke anything to help with true odor detection.
The only vape that doesn't smell is a new and unused vaporizer. Sure you can clean some of them really well, but they still won't pass a dog's nose
