Geekvape's Customer Service is hands down the best I have ever dealt with. I bought the Aegis 200W Legend on 09/14/18 from a local Vape shop here in Indy as an early Birthday present to myself. From set up on that day to Saturday afternoon I notice the Battery Life sucked. I went to the same shop with a friend and when I brought this up to the guy that sold me the Aegis all he said was, and I kid you not, "Huh" then walked off. From the time of purchase on Friday untill 4 AM that following Sunday I was upset with the Aegis. I had changed the batteries 9 times so I emailed Geekvape directly thinking that it would take a week or 2 before I got a response. If one at all. With in 12 hrs one of their Customer Service Reps had contacted me. We discussed a few senerios of what could be going on and it was a simple matter of updating the firmware. This Customer ServiceRep was not only courtious but they were very professional, would not back don from the "good" fight on this issue and contacted me later to make sure that the Aegis was working properly. This kind of Customer Service that alot of these vendors needs to learn from. Especial the Vape Shop I went to. Way To Go Geekvape. You definitely have my business. I am VERY HAPPY WITH MY AEGIS
