Review (1/5): They felt like used blades.
I've been shaving for close to 50 years, and without a doubt, I've never had a worse shave. I don't normally write product reviews, but having just used two of these for one shave, I will certainly be throwing the rest of them out. The only thing positive to say about them is that I didn't bleed at all, probably because they're not sharp enough to cut my skin.
