I recharged my batteries after 20 hrs of usage didn't want to wait till they totally died. I'm very happy with that. I now wish I had gotten the one with the meter, but I thought it would be even bigger. I was wrong.
Hey Jude... It's a good thing I got it with the Meter mod... Bcoz I just feel that it's easier to just have a readout... My hands are not very delicate... So I tend to over adjust my dial by a huge difference...
