I'm not ocd but I thank you that are. I view everything as a user, whether it is a tv, flashlight, toaster oven, or knife. As long as it is functionally good, I'm good.
I feel the ocd types keep the sellers on their toes, making my purchases problem free. An off center blade doesn't bother me but a blade rubbing a liner is unacceptable. The ocders that keep manufactures worried about off center blades, ensure that I don't get one that rubs.
So, thanks.
