I bought this set to replace an older screwdriver set that I had purchased a couple years ago. I was working on a DS Lite project that proved too much for the older set because it started shredding the bits, rendering them unusable. Only time will tell how the bits from this iFixit kit hold up, but so far they've been able to do the job that my last set failed at. I'm not sure how it works through Amazon, but iFixit provides a lifetime warranty on their products so if the bits start getting shredded I'm assuming they'll replace them, or I can at least go to a hardware store to buy replacement 4mm bits and they'll fit perfectly into the case and driver. In terms of value, my last set was cheaper but it also came with less bits, but a metal driver. In terms of bits-per-dollar, this is about the same value. You can buy cheaper sets that come with quite a bit more bits, but the cases aren't always as nice, and the quality of those bits can be questionable. At the very least, with this iFixit kit you get a nice case that can also be used as an organizer for screws (it works very well for that, might I add), lifetime warranty, and at least decent-quality bits. I was skeptical about the plastic driver but it actually feels pretty sturdy and has better grip, more girth, and a stronger magnetic connection that my last set had so all-in-all I actually prefer this plastic driver to my previous metal one. If I find myself using this a lot, I might buy the aluminum driver from iFixit for $10 but for now I really don't feel the need to do that. This plastic driver has a compartment for storing up to 3 bits as well as an included SIM card release tool. I don't use that, but I can see how it'd be useful. I was originally deciding between this one and the Mako set. That one has more bits, an aluminum driver, and an extender so overall if everything else is of comparable quality then that one is definitely a better value for $35. However, I value small form factors, portability, and not having unnecessary things lying around that I won't be making use of, so for me I think this is a better fit. I'm mostly using it for retro Nintendo handheld console repairs, and the variety of phillips and tri-wing bits that come with this is plenty for my needs. I've only used it for two projects, but overall I'm really happy with it and recommend it if you're on the fence because for $20 it's a good package. If I find that over time this is a really disappointing product then I'll adjust my review.
