Summary: I bought the 18v Lithium Ion Compact pro Driver because I was building a deck and I knew I would need something to drive the lags in for the ledger board. I did not disappoint! The only reason I didn't give it higher ranking is because the charger doesn't seem to work. Luckily I have a 18v Lithium Ion Drill with the same charger.
Summary: I purchased my first impact driver about a year ago. When the switch went bad,I purchased a second unit while I got the first unit repaired.The authorized Hitachi repair center tried to charge me 75.00 for the repair.Hitachi steped in and helped me retrieve my "hostage driver" without paying the ransom.
Summary: The first time that I used this tool I was blown away. Could not get over how powerful this driver is along with the lightness and power. I had to use this in my 4/12 pitch attic and needed to spend as little time as possible because of the heat build-up. It performed beyond my expectations.
