If I didn't have like a decade's worth of wax pen knowledge built up, I'd probably pick up a Proxy. I like sitting back with a little device and taking little dry low temp dabs. Unfortunately, I'm certain I've put together a superior dry electric hash pipe with parts I have around the house:
I'll still try to give the Proxy a whirl at some point, but I'd be shocked if I like it better than this. For one, my hash pipe uses black SiC instead of white ceramic. And it's true what they say. Once you go black (ceramic), you never go back. The DTv5 tastes great. The M22's SiC just tastes better and smoother. Can't imagine it'd be different with the Proxy's white ceramic.
I can swap batteries instead of waiting for a charge. It gets to temp in 4 seconds instead of 30. And while I'm using wattage curves instead of temp control, I bet I still have more temperature customization. Several reviews have mentioned the Proxy requiring reheats and leaving a puddle. Never a problem with my little guy. You can take the equivalent of a hot, cold start torch dab, and the sapphire cooling balls will still make it pretty comfortable. No water needed.
Total cost of my hash pipe is about $130 new. Unless you already have an old Pico laying around. It requires a little knowledge to get it going and keep it maintained, but the ongoing cost of ownership is low. Replacement Proxy atty's are $60 a pop. And once the battery goes... you'll need a new $300 device instead of a new 18650.
I'd also rather look like an e-cig douche in public than whipping out a device that is definitely for drugs. The time's they are a changing, but old habits die hard and I'd rather not encourage second glances from law enforcement.
