I can add little to the other - mostly - glowing reviews of this product.  Notwithstanding what others have said, my view is that the cleat runs SLIGHTLY small, so you may need to add half a size to what you normally take.
I referee rather than play, so admittedly do not subject tham to the same abuse as others might, but my first pair lasted several years, and to be honest, I am replacing them only because the leather became somewhat stiff - my fault for not treating them every so often.
