This is an excellent tool if, like me, you occasionally want to change the strap on your watch.
Obviously at such a low price it isn't the same quality as a Bergeon spring bar tool Spring Bar Remover Tool Bergeon Swiss
or even a cheaper Hirsch one, but at roughly 20 times cheaper it will do fine for me.
I have only used the forked end and the other end of the tool, a bracelet pin remover, is a little bendy so I would be a bit hesitant to use it for fear of breaking it and getting it stuck inside a bracelet link.
Ultimately, it does the job and is much better than trying to remove spring bars with a small penknife blade, which nearly always leads to a scratched watch case and bleeding fingers!
