HISI !!!! One of my Favs

I really enjoy buying these downstems from 420science rather than hisi main website, because 420 science has better packing and shipping and way better quality check before sending it out... PROS... lots and lots of percalation fat hits lots of taste Cons.... Hisi Glass is not really that strong Conclusion Love hisi glass

Diffusers are the best

I bought an ash catcher that came with a diffuser slide, and quickly realized I needed one for my piece as well. This slide takes up all the space in my piece and is a near perfect fit for a 15 inch bong. Diffusers are definitely better than normal slides. This slide feels somewhat fragile, so I'm going to make sure I'm careful with it.
