Currently I hate this thing.  I may need to oil it/adjust it or make some other modifications but it squeaks of metal on metal and cuts about 1/3rd of the grass I pass over with it.  I found a manual mower like this in the yard of the first home I bought and used it for years.  It was better than any mower I've ever owned.  This seems to perform like a cereal box toy imitation of what a manual push mower is supposed to be like.  Pooptastic.  I will update this review if I am able to modify it to actually cut grass, but out of the box it seems to make far too many blade passes per distance traveled to ever perform well.  Also the last model I had had two counter-rotating blades and this only has one rotating in one direction against a stationary blade/block.
