It's a replacement part, so there's not much to say. Since it's from Norelco, then it ought to work as well as the original heads. That they do. If you have sensitive skin, like yours truly, it will take a few sessions for it and your skin to get used to each other. Afterwards, it works just fine.

This was the third set of replacement heads purchased for this razor. The new heads always return the shaver to like new condition. I replace the heads once per year. The order arrived in a timely fashion without problems.

My razor is again performing like new. I am well satisified with these heads. They cut at least as well as the heads supplied with the razor.

One thing I have learned is that I can't go a year between replacing the heads. Fortunately Amazon now offers a program to send the item each time interval, up to 6 months, that you specify. I signed up for this to be sure that I will get new heads every 6 months for a price below the listed price and with shipping free.

This is the third set of replacement heads I purchased for my shaver and this set seems somewhat improved over the last set.

I am disapointed in this product . It seems to me that the old blades cut a lot cleaner and closer than the new ones.
