This thing totally caught me off guard. it packs a huge punch for its size. as ive read before its harsh and then it gets better with use. but its great. idk if i just got a screwed up bowl or not but mines mishappen. if anyone else has a m420 check if your bowl is like mine cause im pretty sure its not suppost to be that way. also it came kinda dirty when i got it so i washed out the tube not the other part. also is there a way to get like into the metal part because there seems to be ash piling up and fast.
