Review (1/5): Very poor product.
I bought these to replace the original blades in my shaver that I have been using over 2 years thinking they would be an upgrade. They were not! The number of cutting surfaces was much fewer than the original and my shaver worked worse than it did with my 2 year old blades. Just not as good as original and a waste of money. I put my old heads back in! I would like to return these for a refund.
