I started on Volts. Nice little devices, I still use them on occasion to test new juices (cart filler removal trick). Never had a problem with them, just not enough vapor. Moved on to Ego's but I got tired of the short batt life of 650Mah, so I bought twists. Nicer. NEVER had a problem with a single one I bought. Very dependable, versatile, etc. Really all I ever needed. Then I saw pictures of Caravela's. Oh, Mod Lust! GORGEOUS devices, and with a kick?! Who could want more? But to be practical, I don't want to carry around a Rembrandt outside of the house. So I decided since I was moving to 18XXX batteries anyway, I wanted to be done with Ego chargers and just have one set of chargers. I have two homes, and travel a lot. I can't carry all that stuff and I want simplicity. So I decided that since I was going to go 18XXX batteries, I'd get a Provari for on the road. Not that they're cheap, but at least they're production, and I can get a new one quickly, should some catastrophe befall it, unlike a Caravela.
Bought one on Black Friday. Received it Cyber Monday. Screw fell out of the LED window Wednesday and the plastic caved. Contacted CS, who offered to sell me new screws for a brand new, clearly faulty Provari Mini. I protested. Oh, they missed the fact it was new, despite the order number being RIGHT THERE in the email. Grudgingly sent me ONE little screw, God forbid I drop that nanoscrew trying to get it in. Hey! No backup block to thread it into! So there was the problem. The screen protector it shipped with was the only thing holding the screw in in the first place. So now I'M out $12 for priority shipping with insurance and signature confirmation to send back THEIR POS. Am I alone, no. A friend had one exactly 48 hours longer than my 48, and his battery post has fallen out.
Obviously, there was a production rush before the Black-Cyber weekend and quality control was OUT the door. CS was not very accomodating until I had a fit. Now I find this:
eGo Variable Volt/Watt APV V2 (Only Body) [D-B4 APV] - $39.00 : Healthcabin Electronic Cigarettes - Wholesale and Retail
VV, VW, 18350 mini to matching 18650 maxi, will run TWO 18350's, all the circuitry of a Provari including ohm, volt, and short checking. $40. Same quality? I dunno, will it last more than 48 hours before I have to return it on my dime? That's MY litmus. But since I can buy FIVE of them for what I paid for the pro-v, why should I care?
