I use them frequently with my drill, impact driver also by plugging the into a manual nut driver handle. They appear to be made of very good quality and seem to be very durable.

Strong magnet, easy to read size indicators, strong magnet. It's so simple but the sleeve is such a nice add. Magnetic tips are amazing for holding a bolt and starting it in awkward places. Strong magnet to hold screws.

A couple of things that set these apart from the dewalt set is the storage rail which is great. Having been disappointed by harbor freight junk and disgusted with dewalt & milwaukee prices, this set is my go-to choice on the job.
