No more the over priced Gillette or Schick, just a good old fashion razor at a good price, enough said

Having been sold a recent locally promoted product which turned out to be an awful Chinese copy of a big name brand,I went looking for something better,and up popped KOS,A brand I had lost contact with years ago. Shaver arrived promptly,and from day one it was the greatest,a good close shave,no chafing,smooth to use,and seems to hold an edge for a long time. The best I have used in many decades. As a plus,they seem to be made in England,not China.

I finally ran out of blades for my old Azor and had to get a replacement. I'm very pleased with this razor, it gave a good close shave with no cuts or nicks around the chin.

I think this is a great razor. Easy to use, nice feel, not complicated and blades last well

Can't say I was impressed with this razor. After using the Azor for many years this felt like a step backwards. Not enough flexibility and very easy to cut yourself.
Going back to the Azor. Just hope you keep supplying the blades.
