This Review Title is Brought new life to my Hatteker razor and the content is: I was beginning to think I needed to purchase a brand new razor (even though I purchased the Hatteker cordless razor only 1 year ago).. I was so impressed with the razor when I got it, but the blades obviously dulled over the course of time. It just didn't shave well at all. This replacement head works perfectly and my shaver works like new again.  The head is relatively inexpensive, so I will be replacing again when it becomes dull.  Considering how much I used to spend on old-school stainless steel blades, this is still a bargin..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
