Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
The shaver cuts closely and is easy on the face. It does seem to take slightly longer to achieve a close cut. I had my previous Philips shaver for 8 years and it was very good. Recently the frame holding one of the three blades kept falling off, so I had to ditch it. I see that they have also made the cover fit tightly, definitely an improvement.
