I almost never write reviews of Amazon products that I buy, but these bladws deserve a comment. I'm always leery when a manufacturer releases a "new, improved" version of something, which often just means that the marketing department has been told to bump up sales. But these blades really are an improvement over the precious version. The blades are sharper and they definitely give a smoother, closer shave. They seem to last longer too; I've been using the same one for weeks now. I highly recommend them. They're great.
