Hey TRVB not sure who does your glass blowing for the PN WT, but they do an awesome job. Mine is virtually flawless, I think there may be one bubble on the whole thing. It's perfectly straight and stands mostly level. There's a very slight amount of wiggle, but nothing I'm concerned with.
I haven't measured the glass thickness with calipers (loaned out), but it's at least as thick as my SSFG travel beaker. Actually
feels thicker, but I could be wrong.
I'd prejudged the perc through my research as rudimentary, but it's actually nice and works quite well. The slits are nicely spaced - I counted eight. Most importantly, all fire when the PN WT is filled with enough water. I fill my PN WT with roughly two tbsp of water.
The splashguard works tremendously well, provided you don't inhale too hard. Having the Lev lattice bubbler has helped train me away from the traditional bong approach of hauling with all my might on the MP to fight the chug. A slow, smooth but steady inhale is all that's required from the PN to percolate fully and avoid water in the mouth. I've not swallowed any water since getting this piece.
Finally, I'd be remiss if I didn't mention the size.
It really is fucking tiny. I measured it at 5.1 inches, which is about 13cm. That makes it 2.5 inches shorter than the aforementioned SSFG, which itself already felt tiny in my hands. It's also slightly shorter than the Solo with a GonG stem inserted.
This post really got away from me so I think it's best I stop here.
TL;DR I like the PN WT.
