I got this as my second pipe from grasscity and am overall satisfied with my setup: I got it 20" / 14.5 / ice piercings and got the blaze glass 11-arm perc ashcatcher for a double-filtered zero-drag setup with a ton of ice. Unfortunately, the downstem that came with it had a builtin hitter piece that wasn't even diffused so I had to get a real diffused downstem for the ashcatcher at the store for $30 so I'd look around the website to see if you can find one for cheaper.

Now that it has a real downstem tho, it works perfectly: ascatcher has many arms so it clears very quickly, then uncovering the carb makes the smoke all go through over a foot of ice (crushed if possible), resulting in a filtered a cooled hit that feels like nothing. Also, the base is actually steady enough that the bong can stand with accessories on most surfaces, and the glass quality is wonderful.

This is my second G-Spot Chimney - my first was about 5 yrs old and unfortunately is no longer with us. This model seems to be upgraded - wider base and the stem is higher allowing for more water. Two things that also help reduce center of gravity. Super sturdy and outperforms other glass-on-glass pieces costing $100 more. Their bowl/stems can be awkwardly large but easily replaced.
