TL;DR: After exhaustive research and comparing numerous crimpers, I went with these for a good balance of quality and price, not wanting to spend a fortune since I don't use them professionally but not wanting something cheap, either. These are great because they are good quality, you get a lot of capability from the included dies, and presumably you can use other dies to expand your crimping options. They work great for computer power cable terminals, work well, and the company has great customer service. Based on my research, I think this is probably the best value, with (slightly) cheaper options being of questionable quality and better quality options being much more expensive, and almost certainly not being 2-3x as good for costing 2-3x as much. Highly recommended for hobbyists and probably even professionals, with one caveat: I've experienced the dies getting stuck together to the point one of them is pulled from the jaw's quick-release mechanism, and while it's happened only rarely for me (typically when doing a crimp wrong), at least one other reviewer has had the same issue, and for them it happened a lot when crimping insulated connectors. So be sure to test that out right away. Full review: I spent many hours over the course of a few weeks researching crimpers before finally deciding on these, and I definitely feel I made the right choice. I wanted ratcheting crimpers, to help make good crimps, and that's what most people recommend, and it definitely helps a lot. I also wanted quality, but since they're something I will just use occasionally, as a hobbyist, and not regularly as a professional, I didn't want to spend a ridiculous amount of money (there are many crimpers for $150-200 and many for much more). But looking at the cheaper options, I found lots of reviews saying similar things about the dies being poor quality and breaking easily. While many crimpers use compatible, interchangeable dies (which is something I definitely wanted so I could just buy a die if I needed to crimp something else vs a whole different pair of crimpers), I figured I was best off buying a set where at least the tool itself is good quality, so if the dies break I can just get different, better ones, but of course try to find a set with decent dies as well. My primary intended use is for various insulated and, especially, non-insulated terminals used in automotive wiring, computer cable terminals (SATA power, molex, fan connectors, etc), and, if possible, Anderson PowerPole (APP) connectors. I went with these for multiple reasons. They're highly recommended in forums, well-reviewed here, don't seem to have quality issues with the dies like others in this price range, they're made in Taiwan (I prefer made in the US, and I think these used to be made here, but I prefer Taiwan to China, party due to the fact it's generally better as far as quality, and it seems S&G still has them made to high standards), they can go all the way to 22 gauge non-insulated, replacement/additional dies can be easily purchased individually for relatively cheap, they can do coax, and, of course, the price is great for what you get. Also, S&G appears to stand behind their products and improve them, as evidenced by the fact they changed the quick-change lever from plastic to metal after complaints about the jaws separating sometimes and causing an incomplete crimp (which, by the way, was the only common issue I saw with these). And while I haven't confirmed it myself yet, I'm fairly certain it will accept other manufacturers' die sets, which means it could probably even do Ethernet, which only leaves APP, and I think they might work with a couple dies I found for that. One is the Andy-Crimp Pro Die (gsradio), which would be great since it's apparently one of the very few with the ability to do 75 amp APPs, but I have my doubts about this one, since the holes on the APP die are decentered more than the ones on S&G dies. The other is an MGS 7505-DIE I found on eBay which looks more similar to the S&G dies as well as those of other brands, which can also supposedly do 75 amp connectors. The dies can also be placed in any orientation, so you can put the part you're using toward the front or back and so the terminal goes in rightside-up or upside-down. I didn't realize this until I just tried it, because they're not symmetric so I just assumed you couldn't put them in backward. It certainly would have helped with some of my crimps had I figured it out before, so I wanted to mention it. I've used them quite a bit now for making some custom computer cables, and for the most part they've worked perfectly. I've only had two very minor issues with them, and both are probably user-error. The first is that they were bending the SATA power terminals, which didn't cause any harm, but was a bit annoying and made me think the die should be designed a bit differently. I contacted S&G support, and we emailed back and forth several times. They responded quickly and were very helpful, and we decided I should try a #18937 (non-insulated open-barrel terminals 30-18 AWG including Weatherpack terminals) instead of the #18922 (non-insulated open-barrel terminals 22-10 AWG including Weatherpack terminals) I was using. They even sent me one to try, since I couldn't find it anywhere, though I noticed later one comes with this kit, so I already had it. I didn't even think to check because I had told them what kit I had and it didn't occur to me they wouldn't realize and mention that. Based on the description, it would seem both would work for the same terminal types 18-22 AWG, and I was crimping 18-gauge wire, some with one wire and some with two, so it would seem the #18937 would be either borderline or too small for what I was doing, which is why I went with the #18922. But it did work very well, and it didn't bend the terminals. So for anyone looking to crimp SATA power terminals, hopefully that helps you. The other issue is that occasionally the jaws will get stuck together (it seems the terminal almost welds them together), and one will come out of the jaw's quick release mechanism, so I can't use the crimpers to pull them apart. I have to grab one or both of them with pliers and pull them until they separate. So this problem is twofold: the sticking, and the quick-release not holding on well enough. I thought maybe that was intentional, to prevent damage to the tool, but S&G said they'd never heard of the problem (I'm assuming they meant both the sticking and the die separating from the jaw). The good news is this is pretty rare, only happening 4-6 times in over 100 crimps, and each time it seemed it was due to a bad crimp (e.g. putting the terminal in the wrong way on accident). Still, it would be nice if the release mechanism was a bit stronger and could hold the jaws in place better to make it easier to pull the jaws apart, and this is my only criticism of this set, but it's a very, very minor one. And at least one other review has mentioned this same thing, in their case with insulated terminals. I haven't tried insulated ones yet, but if it is indeed common with them that would be a significant issue, so make sure you test that right away. It would also be nice to have the option of a bag (like the Snap-On below) instead of the case, with room for a few extra dies, as it would take up less room and probably even cost a bit less. That said, the case is well-made and holds the dies snugly, though unfortunately each spot is shaped exactly for a specific die, so if you use one other than the one that comes mounted in the tool, you'll be swapping a lot, since the "default" one won't snap into the case (you could put it in the small space in the corner, but it wouldn't be held tight). ALTERNATIVE CONSIDERATIONS Other than these, I looked at the Snap-On Blue-Point PWC48 (PWC48NJ for the kit, which is what I would get), Powerwerx TRIcrimp with interchangeable die set, Greenlee Communications 1322 Non-Insu
