You are missing the fact that the razor is probably going to get dull by the n-th member, for example. And that people might just dull it with stropping on the first try.

Also - while this razor might shave great, we have discussed variations between same model, etc. razors - so it is not guaranteed that the next razor (that you will want to buy after testing this one) will be as great. Of course, it may be even better than the one that was tested - this is the ideal scenario

Also - if we have 20 members or so - some will have to wait for months! I know where I want to be in the evaluation turns

I am sure other things are missing too but this is off the top of my head

Having said this - I'd pay some $ to try one such razor. ($35 is ~ fine, $60 will be too much maybe)
