Nice Features
Pros: I really like the toggle showing amp draw. I use it on a trolling motor battery and a starting one. The LED says charged, and the AMP indicator shows zero, I know it's charged. The start battery likes to cycle, led goes on/off, but the AMP shows zero, I know it's charged. Plus, lots of choices in charge modes and a start up mode for a badly discharged battery.
Cons: Since the manual says don't clip the clips together, don't clip them to the handle or the cable, but coil them up neatly, it would be handy to have something to wrap the cords to like you'd find on a vacuum cleaner for instance.
I'd really like to know why clipping to the handle is a no-no.
