Stopped by on my lunch break today because my mod (Geekvape Blade) was giving me an error (no coil detected) every time I tried to fire it. As soon as I walked in a gal sitting in the lounge area jumped up to greet me (even though she was in the middle of a lunch break herself). I showed her my mod and the error I kept getting and she immediately pulled my tank off and replaced it with her own to make sure it wasn't a mod error before having me shell out any money! Fortunately my mod read her coil and she quickly grabbed me a new coil to replace my dud. $5 later and I'm thankful for such a cheap fix considering my mod was 80 something brand new! She was super nice, helpful and even primed my coil & turned my wattage down so I wouldn't burn it up immediately! So glad this place isn't far from my work, I will definitely be making a trip back in! Thanks 23rd Street Vapes!
