Bought an Ego One 2200 on 6/15 and 2 days later it didn't hold a charge. I took in back to Hidden Vape in Wells Ca where they said, "Contact the manufacturer in China." I did & after 2.5 months & 52 emails later they okayed a replacement. That was defective also. I contacted them again within the 90 day warranty and they kept asking for the same documents over and over which was sent in the time frame. Now since the warranty time is over they say, "we can't do anything, you're out of warranty". That is dishonest customer service.
