Kaisi 136 in 1 Electronics Repair Tool Kit Professional Precision Screwdriver Set Magnetic Drive Kit with Portable Bag

I needed this primarily to disassemble and reassemble some pocketknives that were getting sticky and not flicking open as they should. Since then, I have found a few tasks that I could do because I now have the right tools for the job. The kit as it is, is a good size to just keep on my desk and it allows me to tinker with things as needed. My brother "borrowed" my kit to build his computer. he was impressed with the quality, hardly believing the price I paid. Keep in mind, these are in my opinion not the "highest" quality tools BUT they are very well made and the price point makes them an exceptional value.they are *not* soft, disposable, single use, strip and smear, type bits BUT if you torque on them hard enough I can see them being ruined rather quickly. if you need a breaker bar to remove your micro sized fasteners you probably need another tool or try turning it the other direction. If you are easy with the tools, slow steady pressures... they should last for a long while. you can break just about anything if you try. lolthe add in pieces feel like the bonus nachos. they are there, but not the reason you buy the kit. those parts are ok I guess. if you need a tiny pry tool or wedge to get in a seam and pry something apart without marring up the plastic they should work just fine.I would have no problems buying this again or recommending it to someone that needs a kit like this. its not a lot of money to lay out and IMO between the repairs that I have done, and the use my brother got from it, I would say that it's paid for its self.

3 YEAR UPDATE POSTED BELOW ORIGINAL REVIEW:Original review:Good build quality, I was impressed with the good fittings between all connectors and the strong magnetism that locks the bits in place. The flexible extension shaft has been very nice for difficult angles. Also, the case the bits come in is well put together and feels sturdy, as well as having the nice feature where the rows will stow down for carry but fold up for easy accessibility. The small bag included for the other tools is also very nice for quick and easy storage. All of the bits and connectors seem to be very sturdy and well-machined. Well packaged and arrived promptly. I will update this review further after I have used the kit more thoroughly, but first use and initial impressions are very nice.3-YEAR UPDATE: 3 years later, I've put this kit through all imaginable abuse short of using them with an impact driver. The bits have held up surprisingly well, the finish is quite durable and even on the bits that have worn the most the underlying metal has remained perfectly intact and free of rust. No warping or deformation to speak of. The tweezers are one of the most useful tools I have in my possession, having held up well to abuse in and out of the shop. The case does a great job of keeping the bits in place when latched shut. I would recommend if you buy this kit to add a couple of drops of oil to the hinge (I used some CLP). It's possible I got a bad 'batch' so to speak, but the hinge on mine had some noticeable rusting on the metal pins even in the arid climate I live in. Leaving the 5-star rating because it's a 17$ kit and for someone needing a basic set of precision screwdrivers that value is impossible to beat for everything you get in the set. Higher quality sets certainly exist but this kit has excellent value with both the extensive bit set and the "extras" such as the spudger or AS wristband. I have yet to encounter any screw heads or even basic security heads in the various electronics I have dismantled, that I have been unable to coax free with a bit included in this set.

This is a really good collection of the mini-scale hex bits, and the little driver for them is useful for tight spaces. It's also nice that this includes spudgers and other tools one often needs in working on electronics. I also lilke the case. While I have various bit sets taht come in hard cases, for things like an on-the-go toolbag to take to a client's work site, a soft rollup case is much more practical (takes up less toolbag space, and opens up flat. I added a few of my own preferred things to it, and took out a few things I won't be using.Some of the spudgers and other prying tools seem a bit too soft/weak to me. Granted, the purpose of the plastic ones is to avoid damaging screens and finishes, but these seem a hair softer than they should be. Fortunately, it's all stuff that is easy to replace, even in bulk supply, so it really doesn't matter for anyone who's expecting to use such things frequently. And the set comes with quite a number of the ones that look like over-sized guitar picks. They're mean to be disposable.The set does include some metal spudgers, and the wide one I have used many times to "shuck" external drives, to use the enclosed disks as internal disk drives later. While the tool sometimes gets bent up a bit in the process, it's easy enough to bend it back. The small-headed metal prying tool I have not used much yet.The real prize in this is the rather wide selectio n of mini-bits, which are compatible with other mini-bit drivers and sets, so you can have a ratcheting one, and a really skinny manual one, and a right-angle one, and so on, all using the same kinds of bits. This set includes a surprisingly diverse collection of bits, including most "security" bit types. One may think "I'll never need these", and it's true, until you need them and don't have them and then you think "dammit, why didn't I get that set of bits?" Like, only last week I ended up needing one of the triangle-head bits for the first time in my life (to fix a Thomas the Tank Engine motorized toy with a loose wire inside it; the mfr. uses the odd-headed screws to keep kits from messing about with the electrical internals). The only down-side is that these are "consumer grade" bits. I'm not sure there even is a manufacturer of bits in this size that are ultra-hard and impact rated, or anything like taht. Every brand of them I find have about the same quality, and it's not too difficult to destroy a bit (especially a Phillips one) with rough and sloppy use of the sort that tends to strip screw heads and driver tips. So, the Kaisi set is simply "standard" for this sort of thing, not inferior (to anything I've found yet, personally).PS: There are a lot of near-identical kits of this stuff. I picked this one because the price was good and also because the brand was recognizable. While not common in North America, Kaisi products are well-known in Asia. Kaisi seems to specialize in tools for soldering and other electronics work, including precision tool sets for working on cell phones and laptops these days. I already had some of their other stuff on my wishlist on Wish and AliExpress when I ordered this (and am now learning that most of their stuff is on Amazon, too, so I don't have to wait for shipping from China or Hong Kong after all).
