Initial thoughts (keep in mind I am fairly new to both vapes and scientific glass):
Wow. And the clouds parted and down came the 187.. VERY impressed.
This guy stacks beautifully and has little drag. The base is nice and solid, with a thicker lip protecting it. I love the flatter top than compared to the D-020, it is easier (for me) to locate the gong and remove.
Did I mention that the perch rocks? Fucking rocks may be a better description. I'm most definitely going towards this before my 20 (I still love my 20, best $30 I've spent all year).
When clearing the 187, it "roars" for lack of better word. The 20 is about an octave higher when compared, almost toy like.
I'm also loving the extra volume in the can. BIG hits if you have the lung capacity.
Only flaw so far is that it tends to splash a bit. I'm running the water about 1/8" about the perc and still noticed a slight amount of backsplash. This could be due to the slight cant in the downstem/perc.
Still trying to figure out how they applied the logo and how I can remove it. Any input welcome. It looks professional for a pirated piece, but I don't want it on there.
Lastly, I'm liking the larger diameter mouthpiece. I'm currently sporting my winter beard and this guy is more comfortable than the 20 or some of my other heady pieces.
