I used this kit to remove a couple of links from my new (Mother's Day) Invicta watch. I did look at purchasing the link remover (blue thingy) alone, which I could have gotten alone for less than $5 from other sellers, but wanted to get the hammer, pliers, and extra pins just in case. I ended up using just the link remover tool (blue thingy) and the mallet/hammer, but am happy to have the remaining tools for future projects. There were no instructions in the kit, and the website to which the packaging directs you for instructions is extremely inadequate. No pictures, no video, no detailed-enough directions on how to remove the extra links to size the band. However, as other reviewers have noted, there is a plethora of independently made instructional videos if you Google some search version of "how to adjust a watch's link bracelet." Choose a couple to watch - I watched the one produced by "Lazy Ass Videos" a couple of times, then just went for it. BTW, I'm really surprised Amazon let me use the word "Ass" in this review - twice, now! Having read the negative reviews, I was wary of breaking the pin on the link remover tool (blue thingy), but there were three spare pins (a total of four in the kit), so I felt I could afford a little trial and error. It was also news to me that the watch manufacturers put little arrows on the back of all of the bracelet's removable links, which show you against which side of the link you should push the screw/cotter pin, and which side it will then exit the link. I went somewhat carefully, but not with brain-surgery precision, and was able to remove the links pretty easily (while sitting on my bed and holding the watch and tool in my lap). But hey, I put on reading glasses, so I wasn't totally irreverent of the whole process. I did wonder if the pin was going to break, as it took a little more force than expected to turn the pin against the screw/cotter pin in the link, but it did not break, so I guess it just depends on the watch and how tightly the screw/cotter pin is held in place. I think that this difficulty may be an Invicta issue. However, it was not as easy to get the screw/cotter pin back in place to reattach the two sides of the band. That took a lot more fiddling, some taps with the hammer, and I ended up using the link remover tool (blue thingy) again, to push the screw/cotter pin back into place and seat it completely. If I had used a third hand to hold the two sides of the watch band in place so that the holes in the link pieces aligned perfectly, it would have been much quicker and easier. I ended up ditching the first screw/cotter pin I tried to reinsert, and the remaining one seemed to go in much easier, although that really should not have made any difference. I cannot complain about the quality of the tools in this kit, as the pieces I used worked as designed on the first try, and nothing broke or even indicated it was close to breaking. In about 10 minutes, including 5 finding and watching a YouTube video a couple of times, I achieved my objective of removing two links and reattaching the band together so that it looks like it was always that length. By the way, none of the other online sellers' link remover tools are any different in design and quality than the one that comes in this kit. The one sold by Invicta is precisely the same design and quality, but costs $9, is yellow, and has as many complaints about pins breaking as all the others. There is only one design for this non-professional grade, link remover tool, so if this is all you need, just purchase it from the seller that works out cheaper for you. I try to only get items that are eligible for Amazon Prime (even if it costs a little more overall, as I get it within a few days and can track it easily), which has paid for itself many times over.
