I've only had time to make a test cut with this saw, but it worked wonderfully.  Smooth, easy, went right thru a four inch diameter wild grapevine "branch".  I also like the shaped cardboard package it sheathes in, it will last for some months with care.  I took note of other reviews and will be dotting the screws with some glue or loc-tite  before using it heavy duty later this season.
