Review: Love it. I manage to fix my xbox elite controller with it. So it paid for itself 10x over.
Review: 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 desertcart, too, so I don't have to wait for shipping from China or Hong Kong after all).
