    I have this with me all the time! Easy to use, great grip, power and very light. I am a beginner builder and still trying to add to my tool collection. So far I have built a storage bin for the porch, garbage bin, addition on barn, chicken coop and now a "she shed"!! I absolutely love it. I would recommend this for everybody!!!

    About the DeWalt 12-volt Impact Driver.

    I found (and then bought this tool [a Kit: DeWalt 12-volt Impact Driver / Drill / 2-batts / charger / bag] on a discount table about 4-5 yrs ago at HomeDepot.

    I almost DIDN'T buy it.

    The reason being, I hadn't used or ever seen - or at least noticed Impact Drivers being used by others in my trade; or for that matter the other trades (I'm an electrician). I knew that auto mechanics used pneumatic impact drivers/drills - that's it].

    I was really ignorant as to what an Impact Driver was capable of doing. But because the price was too good to pass up, I 'took the chance' and bought it anyway.

    After I purchased it, I don't think I even tried using it for a while; not being familiar with it.

    But once I gave it a go...Wow! Was I glad I did! And very glad I decided to buy it!

    Skipping everything else I could say about this little 12-volt champion; I'll just say that I rarely, rarely use my drills now...only when I really need to use one. Usually when I want to or need to use my older NON-quick change drill or Uni-bits. Otherwise, it is Impact Driver all the way.

    Recently I bought the 20-volt DeWalt Impact Driver & Drill Kit (discounted again from HomeDepot). The 20-volt naturally has more power than my 12-volt, and I do use it. But for my particular needs, I find myself mainly using the 12-volt DeWalt Impact Driver to accomplish most of drilling and driving needs.

    Why? It is lighter in weight and more compact than all my other drivers and drills; and yet has more than enough power and endurance to handle the bulk of my needs for any given project during any given day.

    I really don't use the supplied handle, but bought the 'loop' holder that clips to my tool belt, and I'm off to the races.

    Lastly, besides the DeWalt 12-volt & 20-volt Impact Driver / Drill Kits; I have the Rigid 18-volt Impact Driver / Drill Kit; and the Milwaukee 18-volt Rigid Impact Driver / Drill Kit; as well as a 12-volt Rockwell Impact Driver.

    Out of and above them all, I find myself using and preferring to use this 12-volt compacted power house: the 12-volt DeWalt Impact Driver. The 20-volt DeWalt is next in line; the Milwaukee and Rigid about even; and I never use the Rockwell anymore (lacks power; speed and will not hook to the belt looped hook).

    In addition. I rarely use any of the drills that came in the kits. The drills I use the most up to this point have been the 12-volt & 18-volt Milwaukee Hammer Drills for drilling into concrete.

    Well done DeWalt.

    Now about LOOSING BITS:
    Yes. Sometimes my quick-lease bits are ejected from and go falling to the floor from my ladder. Meaning, at times, when I have NOT BEEN CAREFUL, and I place the nose of my Impact Driver into those holes supplied in the top of my ladder. The quick-release mechanism can get caught and it CAN eject the bit onto the floor.

    Yes. It is annoying when it occurs. Its rather rare, though, I get it caught that way. I've learned to be careful not to just JAM the Driver INTO the ladder hole (or with some quick release mechanisms, if you YANK IT OUT of the ladder hole without being careful). But for me, even not being that careful, rarely does it get caught in such a way that it expels the bit.

    Another worse scenario: Being in a HOT ATTIC for example. While drilling, say, a hole down into the top plate of a wall with my Impact Driver. If while PULLING the Impact Driver's nose UP out of the hole; I fail to be conscious NOT to allow the Drivers Quick Release mechanism to get hung up on the side of the newly drilled hole I made. I may end up seeing (or hearing) my favorite bit goes plummeting down into the wall (perhaps, never to be seen again).

    Yes. That is more than annoying! It has happened to me. Yet for me, many of the times this has occurred to me I have been able to retrieve a 'lost' bit with a powerful magnet on a string or rod (but not always). It is rather rare though, that this has happened to me over the years.

    And frankly, it has occurred more often with a DRILL, where the bit has come loose during drilling. It might not be loose enough not to continue drilling; but loose enough, that after cutting all the wood away (that was keeping the bit from falling) - there goes the bit!

    All in all though. I trust a quick release mechanism, more than a drill chuck to keep me from loosing a bit. I'm just very careful if and when I may need to stick the quick release mechanism of the nose of my Impact Driver into the hole in the wood, drywall, metal or otherwise...PLUS, I carry an extra bit with me just in case. I often say to others or a helper, "Take an extra one of those [whatever bit or part]: One to drop or loose; one to use." Murphy's Law is ever present. But sometimes you can out wit it...sometimes.

    This tool has so much power that it will drive a four inch deck screw with little effort.
    And that means it will do the job many times before the battery has to be changed out.

    I had this tool for about a year and hate it. The bits fall out. I lost two yesterday when they fell into deep insulation while working in my attic. I also spent an inordinate amount of time chasing them down into the gutters while working on my roof last year. Just buy two drills and a bit holder.

    Overall good general use driver
    This one replaces the non-impact version I've owned for several years. I work on community theater sets and everyone who uses my drill is surprised and pleased with the performance. They always figure you need some massive heavy monster to drive screws, but Dewalt has shown that is not the case. If you've got to drive screws all day, then something else should be your choice, but if it's only off and on all day, this one will meet your needs. I've driven 3" screws in dimensional lumber for 2 hour periods without any real problems, but it's more adept and something a bit lighter. A great indispensable tool for me.

    Great Impact Drill
    Replaced all of old drills for entire crew of 120 guys. Now I'm not getting a broken drill every week. Because they were trying to do things that 12v drills can't do.
