I have had great customer service with NPRO dealing with junk batteries and they replaced them no problem, however it took upwards of a week and a half to 2 weeks. Now I have more problems and I emailed them to resolve the problems and they haven't returned any of my 3 emails. It's been 4 days now and I don't have a devise on hand which is killing me. This blows! NPRO is now on my bad list.
