I just really prefer the screwdrivers it has. The scissors are better, too. The Charge I have - the bit holder just doesn’t feel that confidence inspiring. I have carried and used my old Wave since they came out - don’t even remember when that was - at work in a kitchen. I use it a lot. My Charge - same as a new Wave - is used at home, or out and about, if I feel like carrying it. I still like it, but the old is quite nice.
