The idea of having that wide range of bits to cover anything I might run across seemed great to me when I bought a kit like that 10 years ago...
But really, I think I've used one of the robert's bits once. All of the T20 bits, breaking several in one day on a deck (special deck screws for that recycled plastic decking) and then had to go buy more, broke all of the #2 phillips (and bought many more packs of just those, and broke them, and bought more), and used none of the others... Especially the flat head bits, I've just never used an impact driver on a flat head screw.
I do like the shockwave bits, bought a pack working on something after breaking every kobalt brand bit I had, usually after only 2-3 screws. The shockwave bits lasted.
