The one minor criticism I have with the 64-bit driver kit is the cost of replacing lost bits vs getting another driver kit when you lose the bits. It's a lot more now, but the number I included here doesn't include shipping since you can get the driver kit from a few local stores (for many). If that isn't the case, you're not going to get as many chances to lose bits without totaling out the driver kit.

This is nowhere near as bad as the original 54-bit driver kit was, but it's still far from ideal. What would make bit replacement more fesiable (cost wise vs replacing the driver set) is if for say $10, you could replace 10 bits at a time so you can get what you need later or replace lost bits without paying the same amount for another driver kit when you could just ride out the old one, buy a new one and then when it's all gone that's it. It will only be truly "totaled" when you lose 20-30 bits.

Like take for example I have an older Pro Tech toolkit before the bit length was changed. I lost most of it over the course of a few years, so the cost of replacement on the set added up to being cheaper to getting another one, and then using my old one until it's all gone. However, I can still reuse the parts I have not lost yet. I also have a set of bits which match, and no lost bits. That original set was when I didn't track things that aren't "consumable" well, but I consider them "consumable" so I do not count them against the cost of replacement vs replacing the lost part.

It's kind of like how on a laser printer* you consider the printer non disposable, because the hardware outlasts the toner carts. On the other hand, inkjets are usually "disposable" due to the cost of ink, so with that reference in mind, I consider things like the pry tools made of metal non disposable, but the plastic tools disposable.

*Good ones, not cheap junk like the HP m139w which is so bad it lacks a Ethernet port ($159, toner is $47.99 and lasts ~950 pages, 2 will get you close to a new one and you'll get there fast since it includes a starter which is worth more dead).

The math swings worse when you look at the "refurb" 64-bit (Mako Driver Kit - Refurbished - iFixit Store) as an option to get the price down a little. You hit that magic number with 7 bits, rather than 11 -- if you're okay with not getting a box, then you're getting replacement bits, with a few bucks off and it isn't like buying a "new" one since it was previously used. This is like how I got my Lexmark C3326dw for $155 with full "Lexmark SWP" toner (750 starter) which goes for $324 new, and it was full when I got it and I only ran it down checking the color alignment as I ran the diagnostic twice, in error. I basically bought a new printer for a bit over 50% off. I was in the right place at the right time; I was looking for a color laser, and I got one that was basically new.
