Copied from LF website:
Liberty Flights guarantees eGo-t atomziers for 28 days or 30ml juice throughput. (typo and all)
You state you are coming up on 14 days, so you should be more than covered.
Based on what I'm reading here, it seems LF is swamped with work. They might be delayed in getting email responses out to folks. There is also a phone number in the CONTACT section of the website. If I were you, I would give them another day to respond, then send another email. Then wait a couple more days, then place a phone call. You have time on your warranty, so you should be fine.
And YES, Liberty Flights really really really does stand behind their warranty and their products.
Products fail.
Liberty Flights does NOT fail.
Hope this helps a little,
