Well, I think I've made an error in ordering supplies. I first purchased a Metro by Nicotek from my local smoke shop. Wanted to be able to refill with my own juices, the standard carto that it came with probably is refillable but I wanted additional ones. Before I figure out the carto, atty and cart "thing" I ordered this: Electronic Cigarette - Atomizers & Cones - RN4081 . Guessing this is just the atty and I needed a cart to go with it correct? I was confused when first looked at it because the top of it is sealed with only a small hole at the top. Is there anything I can do with this? Syringe in juice or is that a no no with my auto battery? I'm going to have a go at refilling the cartos that the Metro came with but if I can use the atty too, that would be great. Ordered my Riva 510 on Friday so it won't be here to next week sometime
