Got these in an Amazon sample pack, so they were cheap in that sense. Further research confirms that they are indeed cheap. The initial blade is pretty darn sharp, but it doesn't last long.
Long story short, if you end up with them, use them, but I wouldn't seek them out or change from your current blade for them.
