For a product like this - something with a pretty specific function that doesn't do much else - it's difficult to write a review as it either works or it doesn't. I bought a replacement watch strap for one of my watches, and while the strap came with its own spring bar tool, I figured it would be worthwhile to buy a higher quality tool as I imagined the "free" included tool would likely be low quality.
This tool worked well enough: I was easily able to replace the watch band and didn't have any trouble. The fork is quite fine and easily slid between the lugs and strap on my watch. The fork itself was solid without any give despite some relatively high force. The tool as a whole is solid with significant heft and is long enough that holding it is quite easy and comfortable. In contrast, the "free" tool included with my replacement band was extremely small, weighed almost nothing, and I'm skeptical that the fork would last a significant amount of time.
As a non-jeweler who is probably going to use this tool only rarely, it served my purposes and did so well. Is it the best tool around? I have no idea. But if, like me, you just need something to replace the occasional watch strap, this will probably work for you.
