So I broke down after my 510 died and bought the Ego-T kit /w 650mHA battery. I noticed however, that my battery does not have the EGO branding as I have seen pictures on the internet. Also, it seems that after the first initial charge it takes 2-3 minutes of vaping for the atty to heat up and start producing non-dry tasting vapor. I have tried new atomizers, dripping a few drips in before inserting the cartridge, but still the issue persists. Any ideas? Do you think my batteries are knock offs? I also noticed my kit never came in a retail box, it came in a cheap branded case from the vendor I purchased it from.
