First of all, I have a Riva 901 and want to use my 901 LR cartos from Ikenvape with the mini. If I remember correctly, I read somewhere in here that the mini is made for a 510, but comes with an adaptor for the style you want, In my case that would be a 510/901 adaptor. Am I remembering correctly? Would the cartos I'm using now be a good match for the mini? Great Lakes Vapor is out of the batteries, but found some at Light Hound for a good price and supposedly in stock. Have to find a charger somewhere. The one at GLV looks like a good one, but out of stock also. Hate having to go to 3 places to get everything, but looks like no choice at the moment. Anyway, love the looks of this thing, and the reviews are good, so, gonna have to get one. Thanks.
