Got it today... and got it a day early!  Gotta Love Amazon.

This tool is very sturdy and feels it.  It doesn't feel cheap at all.

I have never used one of these, but needed to change my watch battery.  I like to do things myself.  When I opened it there were no directions, but it was easy to figure out.  I had the back off of my watch in 4 or 5 minutes (it won't take so long next time).  It took a little longer because I left the band attached.

Once I got the cover off, I found the battery I needed, replaced it and the cover was back on in just about 1 minute.

If your thinking about buying this you wont' be disappointed.
