I received Enders Speed blade yesterday and shaved with the razor, using the blade as shim for Schick Proline. It was an amazingly easy shave. I was very impressed and decided to use it till the Proline blade wears out, leaving the blade placed in the razor to avoid the hassle of realigning. I was about to shave again a moment ago and what I found out is .... The side tab of the blade chipped off by itself. So that means I have to set the blade in and align it everyday and it really puts me off!!! I was thinking of the razor as one of my regular rotations but I think I have to reconsider it.
