Not a lot to say, the case press does what it should.  It has several different sized dies to give the proper fit for different size press back watch cases.  It is pretty easy to use and figure out, which is a good thing since it doesn't come with directions (the die for the back is flat, you put the watch crystal side down on the cupped die).

There are a couple negatives, but nothing too bad.  It seems to be a pretty cheap metal and it is probably die cast or MIM.  There are sharp corners on the bottom so do not put it on top of a good table when using or it will scar the wood.  If you don't have a workbench or a cheap piece of wood to put it on, at least put down a thick tablecloth to protect the table.  Also, due to cheap materials and construction, I'm not sure how long it will last.  Still, I've replaced the batteries of several old watches I had and it really doesn't take many for the press to pay for itself v. taking your watch to a jeweler or watch repair shop to have it done.

Definitely worth the cost.  For what it is, it deserves somewhere in the 3 1/3 to 4 star range.
