Nice gift! Once you start using them, you will wonder why you didn't switch over to cordless much sooner.
I've been using Milwaukee cordless tools for several years now. The maintenance department at the manufacturing plant I used to work in, switched from Dewalt tools to Milwaukee. The difference was night and day. drill stopped instantly upon letting off the trigger, instead of coasting forever. The chuck on the Milwaukee tools could actually hold a bit tight, instead of constantly slipping like the Dewalt, and having to retighten time and again.
After experiencing the difference, several years ago I treated myself to a Milwaukee drill/driver combo for Christmas. Have never regretted it. In fact, I recently added a cordless 18v jig saw.
Hope you get plenty of use out of the set.
