Query: Unbelievable

I can not believe how badly this shawer works, or maybe i should say DOES NOT WORK. I keep thinking i'm doing something wrong because it is impossible that someone could launch a product that doesn't even come close to doing something it's meant to do, let alone do it well, but i tried everything the manual says. I will give it one more chance with new inner blades but i doubt that will change anything, it should have worked right now since it's new. This is a disgrace for Panasonic. Stay away from this product.
