I have about a dozen 60v batteries, four of those are 9.0ah. For 60v tools I've got the sliding miter saw, air comp, circ saw, framing saw, two grinders and a string trimmer. No issues, totally impressed with them so far. Bought the grinder and circular saw shortly after I first saw them, receipt says Nov of 2016. The 60v platform is not really all that new anymore, mine's seen a ton of use.I hear ya. I'm still on the fence about flex volt. I'll wait a couple more years before I join that bandwagon. Dewalt had a lot of quality issues with those batteries when they launched. For now I'll stick with 20v cordless and corded for very high torque applications. The EClutch that comes on corded drills will save ones wrist.
