Sky Vapors has probably seen better days. I went in for the first time and the gentleman behind the counter (didn't catch his name) seemed completely disinterested in helping me. All his answers to my questions were curt while he stared at his phone. Also, the ejuice menus were out of date, since I heard "we don't have that anymore" a couple times. The tables could have used some cleaning too.
On the bright side they do have quite a large selection of hand-mixed juices, all of which you can sample. Most of them were tasty too. They can also mix in as much (or as little) nicotine to fit your exact preference. Prices are very reasonable as well.
4/5 for variety of flavor and price. 2/5 for customer service. 3/5 overall.
