I've just finished using the Paylak TSA9005 Watch Repair Tool Kit for the first time.  I had taken one of the other reviewer's advice and found instructions on Paylak.com. It only took me about 10 minutes to remove two links and re-pin the band.  My new watch fits perfectly now.  Using the tool has saved me at least $10 already, and I suspect it will save me, family and friends much more.  I just ordered the Paylak adjustable wrench for waterproof watches to replace batteries. By the time I go through my watches that need new batteries, I will probably have saved the cost of all the tools.
