I mainly have dewalt 20v also. Ive got their big brushless impact, which by the way is a amazing if your the one your entire family calls when someone gets a flat, recip saw, drill, impact driver, and weedeater (also amazing since you dont have to spend t min starting the dam thing) I have zero complaints about any of them although ive heard some have had problems charging the flexvolt batteries. I guess some of them will say they are fully charged when theyre not. That being said i have 2 flexvolt batteries and havnt had a problem. I just bought the porter cable cordless grinder and drill because it was on sale through msc and wanted to see what theyre like. Like i said before, i wouldnt be afraid to purchase any WEN corded tools. Our drill press has served us problem free since the day i started working here.
