I've recommended this new Dewalt tool set to many folks. No one has been dissappointed as yet, being this past 18 months of those that has gotten the set. Also, they are extremely easier to handle in roofing jobs where we use the impact driver installing the #12 screws thru the sheet metal roofing into the perlins on Missions trip verses the heavier Dewalt 18 Volt. As a result we have seveal sets with us on our Heartland Missions team here in Oklahoma City.
I use these everyday, I have the drill, screwdriver, impact, two flashlights, and four batteries., all batteries are numbered and in constant rotation.
Installing kitchens, and endless amounts of trim, railing work, storm doors etc. Batteries last most of the day or all day into the next, depending on work load(of course) no complaints, charge quick., for constant light to medium work, occasional 2" hole saw not a problem, would'nt make it a habit though, unless your trying to break it. we'll see what the cold weather brings, I had Bosch's first generation 10.8/12v Li 2005/06 all went dead(fully charged) 5 min in 30 degree weather, not a very productive situation, then Makita, 2008/09/10 no complaints there, worked well in cold but don't seem as heavy duty as dewalt and not as refined of a design, Dewalt feels better in the hand (mine anyway).
Pros: light weight, reasonable duration of charge for the size
Well, Amazing, All The Honda Techs Use The Lithium Ion 12V Max Impacts. And Everyone Loves Them. Ease Of Use, Power, Fast Charging. Time Is Money, And With These Batteries, You Get What You Need From DeWalt!
