OKC Vapes is the worst place to go in the City!! They have about 10 people working with two customers in the store and it still takes forever to get out of the place. First time I went I purchased a EGO Winder 1100 model, after a week it stopped working the light on the button would just keep flashing, so they talked me into buying the EGO 1300 model - it was a better battery - they never have problems with it, blah blah blah. Well I purchased this on 3/4/14 and on 3/16/14 the same problem happens again! I saved the receipt just incase it happened again. So I went in today to get a replacement, first they wanted to charge me $2.50 to test it out? So talked with the Manager he put the Tank on no charge.. lol and he unscrewed my tank to where it was hardly on the battery and told me it was working fine. I told the Manager I wanted it to work the way it was supposed to and he said he couldn't do anything for me that I could buy another one? There all about the money and there juice really isn't anything special, I go thru almost a five pack of wicks every two weeks because they make there juice so thin it floods from the bottom of your tank into your battery. They use water in there juice, a lot of other places don't. Don't waste your money here!! Go check out Vapor kings or Creative Vapor its worth the drive!!
