Falls short of the OEM quality.
Photo shows the OEM blades (my S9000 Prestige) in the upper right with the purple plastic drive pieces, and these replacement non-OEM blades in the lower left with the grey plastic drive pieces.<br /><br />Not "bad", but had a couple of items I thought were noticably lower on the scale compared to the OEM blades. First, the "glide" over the skin as one moves the shaver around doesn't have the smooth, buttery, feel that the OEM blades do. These seem to "stick" a little bit. More friction from whatever the surface treatment is I guess (chrome, whatever). Second, I noticed about a half dozen times while shaving neck/face/head (I shave myself bald), a heavy "grind" noise. It was usually absent, but it popped up a few times.<br /><br />The closeness of the shave wasn't terrible. I had to go over, and over, and over, spots multiple times to get the smoothness I think I want. But I have to do that with the OEM blades as well. But these took "just a little bit more" so are slightly less efficient.<br /><br />If you're looking to squeeze pennies these are an option, otherwise, you'll get a better shave with the OEM blades.
