I would say others comments about this being more comfortable/smoother than a Feather might be correct. Although I got a really nice shave with the Kai DE blades, I don't believe it will replace my Personna Med Prep blades. The one thing I really like about theses blades as I do with my Med Preps, is that they do not use any glue/wax on the paper. Now my question is, if Personna and Kai can wrap the blades without wax, why can't the rest of them do it. Would I buy this blade again, yes I would. I would probably rate this blade #3 right behind my Med Preps and the Polsilver Platinum.

The only comparison I have is Wilkinson Sword, which I have been using for the past year. I've had Some good shaves, but often they feel rough, and often leave me with terrible irritation either side of my neck. Of course this may have been down to my preparation and technique. The Kai's are different. It's a more pleasant shave, the blades are super sharp, and I approached my first shave with nervous excitement. Time will tell, I don't think they will be five star, but they are very good. I'll use them often, but I think I'll still search for the five star shaving razor blade.
