my first hisi bong and im really enjoying it. pros smooth tasting hit very even smoke if that even makes sense downstem if very unique but very symmetrical including the bowl cons the pull is a little tough but not bad conclusion I'm probably going to be using this bong daily because of how smooth it hits!!! the pull is eh but its not bad! still able to take a full bowl with one hit. i really enjoy smoking with these u perk cant wait to try their other products/accessories .

This Hi Si beaker is totally awesome The upside down perks kick *** you get a hit unlike anything else promise you that
