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.
