I have two mods, an MVP and a Vamo. I have noticed that the MVP, which I really like, really seems to drop in vapor delivery about the time the LEDs go from green to yellow. It's still pretty new. Is this normal? Will it improve after a few more charges? The Vamo delivers a pretty consistent amount of vapor right up to the point it reports low battery. I like the look and feel of the MVP, and being able to charge it via micro usb is a big help to me in my truck, but the Vamo really does seem to work better and longer despite only having a 2,000 mAh battery compared to the supposed 2,600 mAh battery in the MVP.
