I got this for my adult son because he's always taking things apart and putting them back together or always fixing something. I want him to have a large variety of sizes of bits or whatever and this set has some very useful sizes!
I'm looking forward to the day that he needs one of these smaller ones and he'll be so glad that it's right there and he won't have to go on the hunt for it. Haha! This set will get every pennies worth of use and I definitely recommend it!
