I'm a trim carpenter (install doors and baseboards, crown moulding, etc) and use the Ryobi 18 volt kit. I first started using them after one of my crew had all his tools stolen and couldn't afford to replace em. All his were Dewalts. After a few months of using them and having no problems I picked up the set. They work very well, the only problem I've had with them is in the heat of Vegas in the summer time the batterries didn't want to charge. They would have to cool for quitew awhile before they would hold a charge. Other than that, great tools! It's been a year and I haven't had to invoke the warranttee. And with a two year warranttee I don't expect to have any problems in the future!
