Received my echo kit today with one 1300 mAh and one 650mAh. I charged up the 650, and fired up the grill, and when the batt was full I filled up a cart. With the exception of one hour for making fresh pico de gallo and devouring the fruits of my labor (mesquite smoked chicken fajitas!) I vaped that thing until about thirty minutes ago. That's about 5 hours of chain vaping!
I have to say WOW! I wasn't prepared for this. I've been toking on a SD Keyring and xl 808 for the past month, and I've really enjoyed all my flavors at 18mg. As soon as I took a drag of 18mg RY4 from the echo I my mouth was overwhelmed with intense flavor, and good Lord what a throat hit! I'm extremely impressed!
So far I'm more than pleased with this PV. Unfortunately I'm going to have to buy some lower mg liquids, maybe non-nic (my 12mg was even too powerful). That's probably a good thing!
