I like the V Max a lot. I am using a Jugz, filled with Primo, with a single coil 3.5 ohm triple punched cart (shows 2.9 ohm on the V Max display). Unit shows that the battery had a charge of 8 plus volts when I first started using it after fully charging the batteries. After twenty hours of use the vapor is just as good as when I first turned it on and the battery shows 7.3 Volts. Smooth, lots of vapor, replaceable batteries, ability to check the cart's ohm, adjustable in 0.1 steps between 3 to 6 volts. PS The great service from the store's staff is Awesome!
Still looking for the low voltage cut off point!
