I got them yesterday! Today, I filled one up and it's lasted 1/2 day on the liquid. The battery is still going good, so I'm hoping it will last a full day. The flavor is great and so is the TH (using CigEasy's Caramel Mocha Delite). I'll let you know after I get the battery time.
These are great so far! But, I have had a little trouble connecting the battery to the charger. For some reason, the threads on the charger seem hard to engage with the battery.
I think the "EZ" button is a huge improvement over the ones that stick up higher than the case. This one is recessed and difficult to unintentionally press. Also, since the case is square cross-section, it won't roll around.
