Problem - Daughter's Boyfriend Electrical Engineer - Idea for gift!
He loved it! Several times while he was at our house, I found him simple pulling out each bit and playing with the two drivers. My daughter said he had to hide them from his Dad. Maybe Dad will get a set of his own.
Oh yes, advice... brought two sets... one didn't get wrapped... a selfie gift to myself! I did fix my daughter's iPhone's power button, but I'm always fixing, cannibalizing, cobbling together something. they will get much use. Got a lot of other bit sets, but these are by far my favorite.
