I might be able to help you with a few of your questions about Provari. When I ordered my Provari--I did order the extension cap and the longer battery, however I would not order those again. I love the size of the mini just as is for me and the battery life is really good on the smaller battery, last me about 14 hours. I did order extra batteries and a carrying case for the batteries from RDT, so that if I am out and about when one dies, I have a safe place to carry extras with me.
I have one with the blue LED and one with the red LED. I honestly like the red better. I got the red on the white one and it just seems to go well, and I can actually see it better in all lights than the blue. I do not have green so can't help there.
I did really well with the vision spinners and still use those occasionally--but will tell you the Provari rocks for me with a Protank 2. I haven't tried cartos with it because they seem complicated.
The blemish section on Provape's site is a good place to check every day or so. I do like the fact that when you purchase from them they give you points that are available to use 30 days later. Those are nice as they bring down the price of juice or accessories etc. a bit. I have found Provape's juice to be very good. A little pricy but the points help there.
I have not had any regrets with the Provaris--I do think they have helped me completely eliminate cigs!
Like I thought. They don't need to and they know it. They ran a 5% off sale over the summer and I was not able to take advantage of it. Drat. Do you have the minis or regular size provaris. I held the Zombie mini but Nashville Vapor did not have a regular one with them. Is there that big of a difference, outside of obvious vape time advantage of the larger battery.
And if I go to the Provape site, should I get the extension cap and the extra year warranty? I know it is personal preference, but really, charging for a different color led display? And I have read about something that is called Tatroe. What is that? Sorry for all the newb questions, but it is so nice to speak with someone that actually has one and is not in the buy 3 of everything camp. I am not made of money and not in the fanboi camp.
