I have a number of other Makita tools, and have always held Makita in pretty high regard.  My 7 1/4" circular saw works great, as does my motorized hand planer, Reciprocating saw, and my plunge router is awsome.  This machine seems more like a toy that a quality piece of machinery. I was surprised to see a little bit of play when the saw was moved into one of the 45 notches. I could pretty easily move it one degrees side to side, unless it was absolutely locked down, and then it was not consistent about being locked down in the same place. When I got the left-hand miter perfect at 45 I could not get the right hand side at 45, and this is a real problem as they share the same fence. I'm not sure if the notch was machined in the wrong spot or what, but it's impossible to cut perfect mitered corners this way.
