When I bought this item, I purchased it along with a grinder (which I'll also write a review for). It only took about two days to ship and after it got here I was a bit confused by the piece because it looked incomplete. Then I realized it happened to be missing it's glass piece.
I contacted customer support pretty much immediately asking if this was the case, they were quick with one email response to go ahead and just ship a replacement piece out. I got that about a week after my initial order between the emails and waiting for it to be shipped out.
The bong itself isn't a terrible piece, the glass and all other pieces come apart for a very easy clean, and the silicone doesn't hold much residue from sessions of repeated use before doing so.
It's not incredibly smooth hitting (though that could very well be my lack of experience) but it does hit nicely regardless. I'm not sure if the glass bowl it was originally meant to come with would've been any different, as the replacement piece they sent me isn't the same but they seem similar, and so it seems that this would be just a one-hitter. So it's incredibly good for solo sessions, which is what I'm often doing so it's proven to be perfect for that.
It doesn't residue very quickly either, which is good if you're less of a cleaner, and more of a smoker but I do recommend cleaning the pipe a bit more than the rest. It does seem occasionally that the bottom point of the l-curve design in it sometimes gets clogged with resin…
