i never really liked anything but the xs charger, last time I used one it started charging my battery at 16+ volts, which is bad, so I stopped it right away, the xs one is spot on everytime, I guess I cant say I hate them all though, but wont risk it
I mean Im willing to spend the extra cash because having to buy a new battery is wayyyyy more expensive than the extra $100 or whatever it is for a charger
