Product review (1 stars): or the blade got dull. I wouldn't recommend this product to anyone
It certainly is overpriced, bought it and it tore the first week after use!
Now I believe this is the Braun 7/9 trimmer problem in general since I've had 3 to 4 trimmers in my lifetime and it took them years and years to finally quit working right and even then it was not the trimmer head or the foil that broke but the motor, or the blade got dull. I wouldn't recommend this product to anyone, it's low quality and high price.
