Summary: What a piece of junk, used it for the first big job I did, moving my kitchen cabinets. Trying to drive a screw, it would shut off than wait to reset, had to charge the batteries constantly Not a good product..
Summary: I purchased a "New" WH18DFL Hitachi impact drill. The first one they shipped was obviously not new, but used, and the batteries would not take a charge. I returned it for an exchange and the 2nd one they sent was exactly the same. My son in law went through the same experience with Amazon and ended up going directly to Hitachi. They told him Amazon sells old overstock and that the batteries have been sitting around so long that they won't take a charge.
Summary: (1) As usual Amazon is excellent. The item shipped within 2 hours and arrived within the suggested time. (2) This is my first time using an impact driver, this really "ROCKS". It is small a little heavy (for me heavy is synonymous with quality) and packs a big punch. As a D.I.Y(er) this tool empowers me. I feel i can do anything with it. So far i have been able to drive 4" lag screws into 6x6 pine as a test.
Summary: I purchased this driver from a local store in June 2010 because it was on clearance for $150.00. The first time I needed to use it, one of the batteries was dead, Hitachi replaced it without issue. I have probably used it for a total of 4 hours until yesterday when I needed to drive some screws into Trex decking. I charged both batteries and was ready to go, one screw and the driver stopped working completly.
The impact drill worked fine. Both batteries did not have any power to hold.

Summary: I started charging the battery since neither batteries had any power in them when I opened the case. Only after a few minutes the charger indicated that the battery was full. It was in fact over heated and after using it for less than five minutes the battery died. Same thing happend to the other battery as well. I had another 18 volt Hitachi charger which has a fan built in to the charger. Still, the battery that has ZERO power would not charge more than a few minutes!
Summary: Hitachi recently switched to a new slide battery system so this old post style battery systen in now obsolete. If you don't care about battery compatability with new tools they introduce then you are okay, otherwise move on to their newer models.
Summary: I purchased this product in early summer. I have used it to drive torq screws into wood joists in remodeling jobs and also to drive 1/4" head, sheet metal screws in the installation of sheet metal roofing and siding. My grandson and I put up a steel carport with the tool. Light weight and powerful. Can't say enough good things about it. Don't expect it to perform on heavy duty impact jobs like removing tire lugs and such.
