Proxy sales have started on Puffo.com and Zeevapor.com (among other sites). The black and desert Proxys have better deals than the Bloom. I don't personally get the flower bowl deal but to each their own. Vapospy has a few places with better deals as well, so don't forget about them.
I recently bought a longer sherlock pipe for my Proxys from Elevar glass auctions on IG. It's a little rough around the edges (literally, I'll post pics when I can) but I love the extended form factor compared to my other pipes (stock or aftermarket). I picked up a DHgate 14mm adapter for my Proxy early on, but I never use the thing. My Proxys are all dry hits only, and I save the wet hits for the Peak Pros as a personal preference. If you only have a Proxy, the rig adapter is a great option.
Since purchasing in April, would I buy another if my vape collection vanished? Oh yeah. I'd order a bloom tomorrow.
My Pro's see the majority of use most days, but there's usually 1 dab per day that goes in one of the Proxys. The form factor is just too good and I love dry dabs. Concentrates are dominating my vaping the last few months and Puffco has covered the majority of those dabs.
