I had a difficult (also very expensive) RBA that I could not get to work, however I wasn't quite ready to give up on it. I came in late Sunday around 5:00, Jake was working and he said he would rebuild the coils for me while I went and got a bite to eat. When I got back he showed me everything wrong with the RBA and even saved the coils I had built for it; all at NO charge! I ended up buying a new battery and was very satisfied with the customer service. Jake definitely made this my go to vape shop/ lounge and I highly recommend it for both experienced and novice vapers.
