I also
love this little "Atomic Perk" paired with the VHW
Excellent diffusion/throughput (max conditioning, no chug, no restriction), smaller volume (rapid delivery) and the dry chamber at the air-entry bottom catches any grinds pass-thru. I still use the hemp fiber to keep even this bit clean but, when I do without, any particulate matter just collects in the dry bottom chamber, never gumming up the diffusion works, never getting wet. This piece is also the perfect ergonomic form factor for the VHW. When vaping the VHW is comfortably situated/directed/held and the bowl is at the perfect vantage point for watching the load, which brings me to another factor in which the Vriptech VHW excels:
YOU CAN SEE THE LOAD AS YOU VAPE.
I didn't realize how much I took this aspect for granted until I vaped with the EVO & Herbie. Understand, I am so very often melting something (e.g. shatter, oil, ice-wax, propolis) on top of (& into) a packed bowl of flower. Instead of this being a mysterious (& messy) process taking place out of sight in the confines of an "ELB" or "magnetic bowl" I am witness to the bubbling, melting and flower saturating goodness and can tune my intake accordingly. Also, my VCB (Vrip Chamber Bowls) are never a mess as I can place a dab smack in the middle and airflow is down. The dabs just melt down and into the flower and come out clean with the load carcass/ABV.
Other vapes may have more bells and whistles, safety features, etc., but, when it comes to pure function, the Vriptech VHW is simply state-of-the-art. If you like auto analogies, it's like the air-cooled Porsche 911 of vapes. Pure performance, be careful.
