I think what I have to say here deserves its own post.
Everyone makes mistakes, so the criteria for judging a company, person's performance etc cannot be do they make mistakes, it must be how do they deal with mistakes; what do they do to remediate mistakes.
I am impressed more than I can say that once CPO authorized the return, and the process that led to the return authorization, that CPO Bosch not only paid for the return shipping, they sent the replacement before they received the defective one. So CPO Bosch has a very high reputation with me.
