I needed a drill bit, should be 20v to have my hands free when drilling screws for blinds, tightening door hinges, latches, the finally popping out and drilling holes in a brick or sandstone wall. Here's what I like and why I recommend it: 1. It comes with 2 batteries. You cannot work extensively and for a long time with only 1 battery. There are many products on Amazon that only come with 1 battery but are more expensive.2. It comes with 10 screw heads (flat and Phillips). Also, 10 extra pieces for screw plugs/so called sockets is just a bonus for the product. The flexible/bandage screw arm will really save your day when working with screws/caps in tight spaces under something you can't remove/or hit.3. Clamping bits: 4 and 6 twist drills. I've used it to drill holes in hardwood, sandstone/brownstone, and brick walls and the drill bits work perfectly! The drill set itself is very light, about 2 lbs. This makes it easy for you to keep the drill steady while drilling and withstand vibration.4. Other bonuses/Kama are: a light drill when working in a dark place or a screw in a hole. It can also be slightly improved, but I don't know why the manufacturer overlooks this: the head of the screwdriver is not magnetic! If you compare it to a DeWalt drill set, the screws stick to the head/tip of the screwdriver and you don't manually keep the screws from falling off. But I found a way to make it work a little better, you just need to find a piece of strong magnet and rub it on the driver's head to magnetize it. Then the screws won't fall off so easily. The price is really attractive. It even comes with a toll bag. For example, if you use the tool for two years, you'll still end up getting your money's worth compared to a $250+ product that lasts, say, five years. but the battery doesn't last that long. Therefore, I would rather replace the tool after 2 years with new batteries.
