This cool item was given to me as a gift. I have tried it out two times and can verify that it works fine. My reasons for selling it are three-fold. First, I do not do concentrates on a regular basis. Secondly, I collect flasks and have more than I could ever use. And third, I could use a little extra cash at this time. It comes with everything from the online package: 1 engraved flask, 1 engraved microG™ (microG Battery™, microG Coil™, microG Mouthpiece™), 1 embossed Polishing Cloth, 1 embossed Carrying Pouch, 1 Funnel, 1 microG Wire USB™ and 1 microG Tool™ + 2 extra coils. Here is the url, if you want to see it on their site: http://www.grencoscience.com/collections/all/products/huf They did sell this for $125.00 recently and have just lowered the price to $99.95. I think most people, including myself, thought this item was over-priced. So, for someone who would really like this cool item, I am selling it for $60.00 That price will include Priority Mail delivery & it will also cover the PayPal fee! (USA only) Final EDIT:: I will let this go for $50.00 Same deal...free priority shipping and no PayPal fee. Thanks again for looking!! SOLD!!!!
