Second item purchased here, happy with fast/streamlined process. Will be back!

I always want to hit this piece in the mirror because that downstem percolates the smoke so beautifully lol. The bowl piece really breaks up the smoke nicely and it really decreases the amount of herb getting ****** through the downstem. So you can really smoke the entire bowl effortlessly, while keeping the water cleaner than usual. The bowl is hard to clean though. You can hardly fit a pipe cleaner inside it. So make sure you have some alcohol to soak it in. My only suggestion for the good people over at HiSi would be to make the bowl a bit bigger so it's a little easier to get a pipe cleaner inside the bubble of the bowl (I hope that makes sense lol). Overall, I give this piece a 10/10. Some room for improvement, but it's definitely ahead of its time and decently priced.

Good quality glass smooth hits

The 9 hole drain pipe bowl piece is simply the best bowl piece i’ve ever used. The 7mm glass feels nice and heavy, especially when it’s filled with water. I bought this over some others brands because its made in the USA. 420 science hooked it up with a nice 1/2 oz pop top jar with a gold logo. My only gripe is that the downstem has a tiny imperfection like a scratch (not even a millimeter long), but it’s not noticeable unless you inspected the entire bong like I did.
