This is a nice sturdy piece with some heft to it. The slide and downstem are polished and the fitment is perfect. I haven't needed to use Keck clips, and I have not experienced any sticking when trying to remove the downstem. It takes about 20oz of water to cover the slotted downstem. I love the diamond shaped hold and built in glass screen since I do not snap my bowls. How well it holds up is still to be seen. The distance between the ice pinches and the mouth piece is 5.25". The inside diameter of the mouth piece is 1.625" which make it great for holding large ice cubes, but this is also why I can only give it 3.5 stars. With the large opening, you have to form your mouth to an unnatural shape to get a good seal. To make things worse, the outside diameter of the mouthpiece is 2.5" with 90 degree angles so the mouthpiece hits the top of your chin and the bottom of your nose making it pretty uncomfortable. All in all, it is a nice piece and I will continue to use it from time to time, but the size and shape of the mouthpiece prevent this from being a daily driver for me. Your mileage may vary.
This Beaker Bong is something I’ve been waiting for a long time I have quite a few pipes but this one is the ne plus ultra of Bongs It’s made of very heavy glass and the shape with a reduction in diameter causing a supercharger effect which increases the velocity of the hit and makes it equivalent to a concentrate hit with flower or better I am enjoying it and would purchase it again
