I've had the new Echo for about two weeks now and it is working great. It comes with either a 650 or 1300 mah auto battery and a 3ml carto that can be refilled up to 100 times. The auto battery is the best I've ever used and it produces vapor and taste as good as the Go-Go. I love my Go-Go but I also like an automatic battery so this PV solves that for me. The old generation auto batteries could be set off by loud noises or frequencies and leaking from cartos or attys could ruin the battery. They also would cut off if you took a long drag on it. This automatic doesn't turn on except from puffing on it and it doesn't cutoff no matter how long of a hit you take. The cartos are like the Go-Go cartos, horizontal bottom coils and simply don't leak if you let them set for a few minutes after filling. They don't burn and they wick extremely well. It is an amazing PV and you can get a complete kit at Cropduster901.com for 50.00.
