After further use, this PVHES is unreal. Still not hurting from the smaller bowl size. Seems to be lasting a reasonable amount of time. Just made it through roughly a 6'ish minute session, working from temp 2 thru 5. Had the bowl near fully-packed, but not entirely. As long as I get 5+ minutes per toke to sit back, relax, and enjoy myself, I'm fine. Still may order a bent/turbo with the regular bowl for when out with buddies, but no complaints when it comes to 1-2 people using it. But I digress...
The clouds are huge. Huge rips, and it feels great going down. Loving the o-ring... keeps that stem sturdy, gives the unit a more robust, solid feel to it. That, in combination with the PVHES has a damn-near perfectly fitting stem situation. Goes in snug, not loose at all... love it. Helps with airflow as well, I'd imagine. The screen is rather brilliant as well. Ultra-fine mesh... little to no gunk on the glass after several uses. Imagining I won't have to clean this bad-boy too much.
On another note, I prefer the bent stem to the straight, but that's somewhat irrelevant to this discussion. Just figured I'd drop that note.
Happy with the purchase. Next up: one of Ed's stems, and another PVHES turbo.
