There is some technique using saws like this. The head extends a long way from it's mounting point so you need to use care in putting sideways pressure on the handle as you cut. Also a blade upgrade may help I don't ever use the stock blade on any saw, the bottom dollar blade they get is good for cutting dirty material that may have metal in it but they are far from an accuracy blade.
I also have to agree with Gee-dub, to an extent. I can use my 10" glide for precise work with a good blade and good technique. is my table saw with a miter gauge better. Yes, but i don't always need that level of accuracy, in fact it's not all that common.
