I received my 510 disposables from madvapes today - quick shipping over xmas. Mark threw in a few goodies as well. (thanks Mark!)
Anyway, it is definitely a regular 510 atty, and as I stated about how the picture looked - it does have the metal mesh base like every Joye atty I've seen and unlike the clean 'washer' base of the SLB/L2/IV 'new atty' that I have. I'd have to guess this is a Joye 510.
The only difference that seems to be from all reports at Madvapes is that the circuitry in the battery may be different - I'll be counting the number of recharges. Some have reported more than 30 and still going. Right now the one hasn't run out and it came with some good USA Mix 24mg Tobacco flavors - 3 carts with flavoring and an empty cart on the atty, (iow, a regular cart just no filler) and a red led. I notice no difference in drag vs. the other reg auto batts that I have.
A regular manual batt works well with the atty. And the charger will charge all 510 batts - ie. it is not proprietary to the batt that came with it - edit: I, of course, can't say this for sure yet - perhaps it's the charger that is limited - so I'll only recharge the batt on this charger - but from other reports if there is a limit on recharges, it's likely in the battery and nowhere else. If there is a cutoff on this auto (there isn't on most 510's) I have yet to run into it even trying to max out a drag.
Even the box is nice - just a box the size of a pack of cigs but the inside has 'inserts' in foam that the atty and batt and charger will fit in. The carts were loose - ie. no holes in the foam for them. But I could see using the foam in some other type case because of the cutouts for the charger, batt, atty with a cart on it. The 'universal usb charger' alone is worth the price.
The vapor production on this is '510 vapor' and much more than the other M9 - 401 disposable. Flavor holds up well on both. And because of the vapor on the 510, this would be the perfect introductory ecig and would certainly fit the intent of the OP and likely any other merchant that might want to have these available or simply sell them - if a bulk price is available to keep the customer price around $10.
