This thing is great. I was worried all the claims were mostly hype. The flavor is way better than anything I have used before, I am using way less bud, and I can use the cooked bud to make brownies later. I use it through my dab rig. Be warned, the flavor is so pure that using it through a dirty water piece will make it taste really bad. I plan to buy at least one more version when I can afford it. I only gave it 4 stars because I've been having a hard time finding a reliable lighter to use. On days like today, when its -30, Im not sure if I would even be able to get it to temp. Fortunately, hardly any smell is produced, so smoking in my room hasn't been an issue. It actually makes my room smell better, and mixing my bud with tea can produce some really nice flavors. It will taste exactly how it smells. The flavor of peach tea actually changed after each heating. It went from tasting like an actualpeach, to a baked peach dessert. TL;DR. Spend a little extra for an xl, or buy an M and a nonavong and swap parts around. The spinning mouth piece is a no brainer if you like things that are more luxurious.
