I've tried three or four Chinese blades in the past, and none were even close to usable for me. The past four days I've used a FlyDear in my daily razor (Rockwell 6S/4-plate), and I'm a bit shocked. Sharp, smooth, comfortable two-pass, BBS shaves with virtually no irritation. Blown away enough that I just ordered 100 from AliExpress ($6.31 shipped). I'll be alternating them with my long time favorite German Wilkinson Swords. Best shaving surprise I've had in a long time.
