That's very interesting, VapieDan. However, it's not all that surprising. sigelei is evolving the marketing cycle of the V5 by reducing costs and selling it for less. I can't remember how many products I have seen during my life that followed this marketing life cycle but it must be in the thousands, including GMC cars, Maytag appliances and Sony electronics.
A photo of your new V5 next to an older production V5 would be really interesting.
By any chance, have you checked the firmware version of your V5 from vaporbeast? Is it SI V2.0a? Does it have Menu Item #9?
Two battery caps or one? This has varied depending on which batch the vendor is selling for years. Vented top caps appeared on some V5s sold by fasttech over a year ago.
As for the future of any tube APV designed primarily for the less than 20W market, who knows? The market for big, expensive e-cigs is changing just like the market for cell phones has changed. Remember when cellphones didn't have LCD screens on them?
I will get back with more specifics tomorrow. Too tired. Only 1 cap the small one. Argh!
