Only problem is that im also very good what comes to loosing bits all over my yard.
Blame the bitholders, or they have a loosy fit and bits keep missing, or the fit is so tight you almost need to wear gloves to get the bit out.
I prefer the first option , that is why I loose bits in my garage behind or under all kind of stuff. Last year I tore down a cabinet and found a lot of bits under it, all rusted unfortunately.
Hey that is why I recommend the cheaper boxed versions, you get 5, 10 or even 25 spares to last you till the end of the year

Before someone claims I am sloppy, my drills in a 60 piece drill set are after 5 years still complete, and for my precision screwdrivers like the Wiha's also all complete.
It really are the bitholders and probably the cheapness of the bits that make them disappear.
