Milwaukee 48-59-1809 M18 18V 6-Port Rapid Charger

I was worried as soon as I brought the charger inside my house, I open the box and the charger was in a plastic bag. Ok I was still hopeful but I used it the next day on a big job site and we need our batteries. As soon as I put 4 batteries into the little charging docks only 2 would charge and other would blink or not even light up. Would charge some of the batteries at all. The biggest disappointment I've gotten from Amazon. Honestly not going to waste my time with Amazon. Home depot is definitely a better bet and waaaaaay easier return process. I'm an up and coming plumber and I can't take these risk like this guy!
