Which reminds me, I went to the drugstore, a few weeks ago, to get a razor and blades; I took a look at Harry’s, I think, and, surprise-surprise, they are priced about the same as the incumbents...
I'll tell you right now, as a person that got sucked in by the look and feel of the packaging at a time I was looking to replace my razor, it is by far the worst most cumbersome razor I've ever owned. The blades rust almost immediately. From top of blade head to neck is just so long (5 blades plus lots of space) and the weird rubberized flex of the head makes following contours of face virtually impossible. Leaves patches of hair. The razor was probably designed by a woman for legs or an early 20s geek that hasn't sprouted facial hair yet. Either way, you'd be better off buying a razor from a dollar store.
That often times "disruptor" is just marketing to get people on board thinking it's novel and advantageous to the consumer. But in reality, after initial buzz, they are mostly just another player in the market offering little in the way of differentiation, including price.
