I read the other reviews that said this thing was cheaply made and was hesitant to buy it, but I think that Amazon had for $3.75.  That is probably less than what a jeweler would charge to remove a watch link, so I took a chance.

I'm glad I did.  This thing is very cheaply made.  It probably cost more to ship it from China than it did to actually produce it.  However it worked like a charm.  The handle turns and screws the attached metal pin into your watch link, pushing the watch pin on through.

The place for the watch band to fit in is not adjustable, and you can't secure the watch in place while you push the pin through.  Those additions would have been nice, but again, this costs $3.75, and I was easily able to hold on to the watch as the pin went through.

Overall, this is a good tool to have, and I would recommend buying one as long as the price is cheaper than having someone else remove the pin.
