you wont break it, ive used it but own the VaporCannon 3g (amazing) and theyre made of pyrex, which def wont break from tapping it. After 2.5 yrs. I finally broke the tip of my whip bowl, the part that goes in the tube) after kicking the wire of the box and knocking them across the wood floor. A little epoxy and its great again. Pieces break, search ebay for volcano parts and they get pricey. Be careful, u should be fine. and turn the temp up so you can use fan speeds 2 and 3 they work well. sorry im ramblin, love vaporizers :vap_smiley:
