I decided to buy this thing after I took my black anodized titanium watch to Kay Jewelers for resizing.  The idiot jeweler scratched the crap out of my band and took all the links out from one side of the clasp instead of alternating...I know what you're thinking: "what the hell were you thinking?!"  I was at the mall already and I was eager to wear my cool new watch!  I figured they sell a lot of watches so their jeweler must know what hes doing.  If I wasn't such a nice guy I would've made that idiot buy my watch from me.

Anyways, bought this puppy and did a proper job myself in about 10 minutes (the jeweler took at least 20 minutes of banging around and cursing in the back work area to produce my watch in the sorry state that it was in). I was also able to replace some of the MORE damaged links with some of the LESS damaged spare links.  My watch is still a little beat up but at least the links are even on both sides of the clasp now.

Lessons Learned: 1) Dont expect anyone to take pride in their work and do a good job for $10USD and certainly don't trust such a person with a $250+ watch.  2) For around the same price, you can buy this tool and easily do it yourself.  Use the correct size pin on the tool (3 small, 2 large included).  Just take the time to perfectly align the pin on the tool and the pin on the watch and push it out in the direction of the arrow on the underside of the band (All watch bands have this arrow).  Once it is pushed out as far as it will go, use a good set of pliers to pull it completely out. Be sure to pull it straight out or you will bend the link pin.  To replace the link pin, insert it in the same orientation (butt first) on the same side it was pulled out from.  GENTLY tap it in as far as it will go with the butt end of a screwdriver, then use this tool to finish it off, again, being sure to perfectly align both pins in the hole.  Simple.

About the tool: It seems durable enough despite its plastic construction.  Also, as opposed to metal, a plastic tool is less likely to scratch your watch.  The tool pins are steel and I didn't have any problems with them breaking.  I am very happy with my purchase.  Having learned never to trust anyone to do a proper job resizing my watches, I am sure I will get a lot of good use out of this tool.
