Excellent selection of bits with a great rachet
This is my to go choice for electronics and computer repair work and works well on knives, multi tools, and other tools I want to maintain. It has pretty much anything you could need short of a number of a number 2 Phillips had due to sizes of the micro bits. The bits are wiha’s standards so I have never had a problem with them deforming from pressure and have a long usage life. The ratchet gives you enough torque to do harder work, the bit holder works great and turns really well and is protected against electroshock. I did add a couple,of plastic spudgels to open devices such as laptops without scratching and there just enough room in the metal case to hold,all the parts together and well protected. and all in one good steel case that holds the whole kit together. Any missing bits are going to be really rare,like triangle bits and certain security bits that need specialized tools, but for 99.9% of your jobs this will do.

Made in China now!
So to sum this up I’m a longtime Wiha fan. They make great tools and some of the best steel used on their bits. However it shows... *country of origin:China* and I contacted KCTools about this. The KCTOOLS rep live chatted with me and told me it’s a German/Vietnam made product... which it was to be fair. So after telling him this he told me he was going to change the listing and HE DID?! But, a couple years back Wiha had moved production to China and with supposedly the same specs and materials as their German branded Wiha. However, we all know China is a quantity over quality and Wiha cleverly announced a “collaboration” with China on a Xiaomi Mijia 24/piece precision screwdriver set. To be fair the set is only $29 (at this time) and I can tell you those bits are NOT Wiha grade. Look at the reviews and you’ll see broken bits and all. My point is after telling the rep this (because I am going to send these back and look into Felo) he insisted on changing the Amazon listing *country of origin:Germany* which is simply it true! This is why I’m leaving a poor review. I can’t (and won’t) speak on the quality because I haven’t used them yet and to be fair the bit set seems to be of quality steel. The ratchet is nothing special and the tolerances seem off. But the ESD seems to be the PICO quality finish I have on an older set. My point being is I don’t know why they’re not being upfront about this? I’m sure people will do their own “due diligence” and see for themselves. But, I refuse to pay $100 for a Chinese manufactured set trying to pass for German made. I got news for everyone Wiha is now MADE IN CHINA... and this listing should not say Germany for Country of origin. But the rep said he was changing it from China back to Germany?! *Poor form KCTOOLS* Edit: So I have a Kershaw Cryo that needs the torsion bar replaced. Problem is I already chewed up two brand new T6 bits. One was a Walmart special (no surprise there) and the other was from an iFixit kit. Well the Wiha bits did there job and performed as I hoped they would, breaking the blue loctite with relative ease. I couldn’t move one of the screws even a little with the other two bits... so the bit quality is definitely there. I lost a good portion of my tools due to a rather nasty breakup so I have some catching up to do, but I will be keeping this set unless something drastic happens. At least the bits were properly heat treated and to be honest that’s really what I bought this for along with the 1/4” adapter. So I’m going to raise my rating because the tools did their duty and that’s all that matters in the end.

Expensive but Wiha makes the best tools
I'm a computer service technician. I work on laptops, desktops, tablets, cell phones, routers, ATM machines, and printers.. This is hands down my favorite precision tool set. The quality of the case, driver, bits, etc are all top notch. I held off buying these for a while, because the price is so high. At first I went cheap and bought the Home Depot HDX 23 Piece Precision Screwdriver Set for $11. The design and packaging was nice, but the quality just wasn't there. So then I bought a set by Moody Tools for around $43. They were made the USA and from good hard metal, but the design wasn't very good for field work. I reluctantly returned them and splurged on this set, fully prepared to be disappointed. I was not. The Wiha set was packaged very well. The case feels solid, not cheap like an Altoids tin can. It's lined with a neoprene type of foam with easy to read labeling. The bits themselves are also labeled. Every bit is sharp and without defects. The handle is light weight but strong. If I look at these with a super critical eye, my only complaint is I wish Wiha shipped these with the PicoFinish driver instead of the standard driver. Otherwise it's a near perfect set for my use. The bits are a little hard to push in and pull out, but that's actually a good thing, because I hate when bits wiggle. I'll probably never use the little wrench, but it's still pretty cool to have. If your looking for a "computer repair tool kit" and your doing this professionally, this is the kit to have. Don't waste your money on a cheap iFixit kit or anything by Tekton, Belkin, or Rosewill. Those kits are trash. If you need a bit and it's not in this set, buy it as a one piece driver. You'll be much happier with Wiha tools, even though they cost four to five times as much as other sets. The quality is just so much better.

After 2 years
I've been using this set for two years now. It replaced a similar bit driver style set from Harbor Freight (of all places) that lasted me years previous. The difference was stark as you might imagine. I have a few consumer sets as well to compare to, such as a Kobalt and iFixIt branded kits and another one I can't remember. I work in IT and handle a lot of assets for corporate lease which leads to plenty of need for good bits. This kit is useful for anything that fits the bits of course, gun work being another standout. I'll start with the pros and here is the most critical part: the bits included with most kits on the market, especially in (US) stores, are just cheap garbage compared to the quality of the bits in this set. This is definitely what you are paying for. If you've had enough reason to use tiny "micro bits" with true consumer level cheap kits then eventually you will likely grow frustrated. That frustration may turn to outright anger at ill fitting or twisting torx bits. Do you know how easy it is to strip a tiny torx screw AND the bit itself into a vortex shaped mess? Hate jamming a tiny hex bit that gives 1/3 of the way before it engages because of the crap tolerances? Tired of pressing down a lot to prevent stripping on a delicate part knowing you're playing with fire? If so you'll probably appreciate this kit. It is exactly as advertised. The bits are exactly the right size, they dont flex, and they work perfectly. Its nice when your bit is the constant and all you have to worry about is the fastener itself rather than balancing between the faults of both. For complex stuff with fine threads and aluminum that bends if you yelled at it too loud using bits of this quality allow you the best chance to disassemble and reassemble properly, likely being no worse for wear. I just recently fully disassembled a Nvidia 2080ti FE with 77 screws and nested screws, standoffs, torx, Phillips, sockets, the works and with this kit I was entirely confident in the whole process and it went back together as if it was never apart. A cheaper set would be a relative nightmare for that. I almost entirely use the ratchet. I dont use the handle at all. I just pull the rachet off the top of the shaft to use it as a regular screwdriver when needed. The tolerance between the shaft and ratchet "cup" is nearly perfect so there is no discernible wobble. This allows me to apply pretty serious but localized force while minimizing risk to the surrounding area. The ratchet itself is decently made and adequate for the job but the bit quality and shaft tolerance does all the real work. All in all its worth every penny. When I first bought them I thought I was really paying an obscene markup for something that will probably be a little better. In reality you're getting something significantly better than the norm... at an obscene markup, but one I'm much happier to pay. Now for my negatives. This is a lot of nitpicking but it adds up for me. The case is kind of neat in a 70's-90's mechanic's style metal sturdy case, but I wish it weren't. Its possible to have a sturdy plastic case that doesn't suck. My main reason for this is its much more likely for this set of tools to be in contact with other things that dont regularly have heavy metal objects around them. For me, I will toss this into my backpack or into an on-site tech bag where they may be other things inside I dont want this little metal brick slamming against, or scratching. Inside the case there is a very useful picture of the case layout... crappily glued to the top of some foam that presses against the bits. Its such a weird afterthought and "badly designed" as much as a piece of paper can be. The ratchet requires two pieces to assemble to function. There is no reason for this except to accommodate using the handle with the same shaft. The handle itself just needs to be redesigned and have the shaft and adapter welded together. It doesn't sound like something that would be annoying but that extra piece to assemble is oddly annoying when you do it over and over. I just leave the adapter on the shaft at all times and have since pressed it into the foam to make a new cutout for the whole assembled piece. The screwdriver handle is the weakest point of the kit as it actually requires an excessive amount of force to install the shaft or insert a bit and its just not a great design. The ratchet is good and clearly overbuilt for the size of the bits but the reverse switch needs to be fenced in or recessed much better than it is. Unless you were a child your whole hand is going to cover the switch and you will inadvertently reverse directions often enough to be annoying. On the subject of being overbuilt it would have been really nice to see a larger set of socket bits. One or two ticks higher and you'd get a LOT more use out of those and the ratchet can handle it just fine. I'm not talking big sockets here but they cut it off too low in my opinion. And on the same subject I wish they included one size larger philips and flat blade so the kit stands on its own more. And finally I wish the bits were better marked. Its not necessary but I'd have gladly paid another $10 or so for them to be more visible and I think most people would too after seeing it in person. The old school feel and look definitely translate to the markings and its not a great thing. I'm going to try a Wera set someday to see how I like their markings, ratchet interface, overall packaging, and more usable socket range. But I'll never get rid of this set, its paid for itself many times over and despite all the crying I can do all that takes second place to the quality of the bits themselves - which are fantastic. I hope this helps someone. I rarely am this opinionated about something on Amazon but I feel like this product is worth the look

Wiha quality
Wiha tools are made to exacting standards. I notice that these bits fit perfectly in every application. Other brands I have used are not nearly as precise, and these bits are also made of much higher quality steel than most others, so they will not wear out under hard use. The case they come in is well marked for sizes and the foam holds the bits firmly in place, so spillage is not a problem. The ratchet and driver are of good quality and a pleasure to use. They are of course more expensive than many other brands, but I find having good quality tools is always worth it in the long run. Highly recommended.

Great little set.
I work at a tech company that makes gas purification and delivery systems. Generally the amount of space available in the electronic control enclosure and the plumbing enclosure is only the amount necessary to fit the required components. So, a small ratcheting driver is a necessity. Surprisingly, finding a half way decent one is quite difficult. Most of the time the bits are made with very cheap metal with "generous" tolerances so that they either don't fit quite right, or they twist due to torque applied. Now granted these bits are small (1/8"-1/4" mostly) so some twisting is to be expected, but these ones I have torqued a fair amount and have yet to see anything of the sort. More importantly is the tolerances on the bit size are exact. They fit into fasteners perfectly so have much smaller risk of stripping a hex, torx, or phillips screw and less chance of sliding out of a flat one. The only issue I've had is the selector on the back can be moved fairly easily when you don't want to, and if you aren't paying attention you can keep going on the thing and wonder why it isn't tightening, when the selector has switched to loosen. A very minor problem that doesn't warrant affecting overall satisfaction. There is a normal driver handle with extension that are really great too. Had it for a few months now and I would absolutely recommend. Don't do what I did and try to use a cheap one that only leads to frustration. Glad I found this one eventually and will not use anything else. It's near perfect.
