Title: very lightweight and powerful
Review: i have two of these 12v impact drivers that we use for metal stud framing. they are very lightweight and compact and have more than ample power for fastening 20ga and 18ga framing members. the batteries last for hours of fairly constant use and they charge quickly. we use these impacts with a 5/16 driver to fasten tek-5 screws into steel members up to 3/8" thick. i've had the same two for over 2 years and have used them and abused them for hundreds of hours of usage. they've been dropped countless times off of scaffold onto concrete and never miss a beat. i am very impressed with hitachi and these 12v impacts get used a lot more than my heavier 18v drills.
