I needed a drill to create pilot holes for the installation from elevated roads. I took a chance despite the reviews mentioning that they break quickly. You were great for the job. I've since installed 7 curtain rods and a few other bolt holes and not a single bit has broken. I used three different sized bits and have other things to use. Everything was neatly packed in a box and all for the price of 1-2 drill bits. If you are looking for a kit to use at home for light work, this is perfect.
