I will admit I am old school I love my various air ratchets and impact guns . I have an old Black & Decker all metal 1/2 " impact and a newer Campbell Hausfeld . When driven by the proper amount of air volume/pressure they are tough to beat . I have a 60 gallon Ingersol Rand twin cylinder compressor so volume and pressure are not an issue . I never have to worry about a battery that is dead or won't charge .
Like many DIYers I have plenty of dead battery driven tools starting with old Makita 9 volts , then 12 volt Skil , then 18 volt Hitachi and Sears ALL needing new batteries ( $$$$ ) . Over Fathers Day weekend I purchased a Rigid brand " kit " which included a drill/mini torque driver , charger and two 1.4 amp/hour lithium batteries ALL with lifetime warranty ....... that's right even the batteries have lifetime warranty . As an added bonus it came with two additional 4.0 batteries which have a 3 year warranty . I have been using the mini driver in my man cave build driving lots of screws and I am impressed .
But when the man cave is done/completed for any car work I'm back to my trusty air tools , if nothing else they sound manly !
