Several YouTube reviewers and forums have gone pretty nuts over the OneBlade razor -- both in its premium Genesis form and more affordable plastic-head Core version. But take a look at that online source of customer reviews called Amazon. Wow. Out of 59 reviews for the Core, a full 42% are one or two stars. Those are lousy, hate-filled reviews. For example, "I just end up getting irritated, facially and mentally;" Or "the blades can slip past the guides and cut your face ... badly." Many of these reviews seem to be from long-time DE fans looking for the latest innovation, not inexperienced newbies coming from cart land. I had been considering getting a OneBlade for something different in an SE razor, but after reading these fiery opinions, no way.
