My results mirror those posted. I might add, that like the 2011 Muhle R-41, you have to be careful or the Mongoose will bite. I'm using the Feather Pros and I don't know how many shaves, but a lot out of one blade. I intend to try the Feather ProGuard blades. I hear that they are a bit more 'mellow' and forgiving.

As far as buying a Mongoose, if you do buy one, and you don't like it, I imagine you'd get your money out of it with no problem.
