Well, it's not a DNA 20 device, but I am loving the 3 day battery life of my iTaste MVP 2.0. It is an internal battery, but it's very high quality and will last you a long time. It works great with my Protanks and pretty much anything else I put on it. Also, it's cheaper and there isn't a 3 month wait list to buy one! Just my

! Good luck!
