It was a perfect replacement part.

Contrary to manufacture, you can expect one year or less service from a cartridge. They shave well enough, although nothing beats a razor cartridge.I was not sure these cartridges would fit. It was a tight snap, but went on. I oiled them up before use, and shaved. It was nice having a smooth finish when done. I'm hoping I get more than 9 months use out of each blade.

The replacement head fit and cut just like the original shaver head.

These blades are affordable. That takes care of the good. They fit the shaver but it's not a 100% fit and the shaver noise is much greater as a result. They are also not very sharp or durable. The shaver with the original blade gives a nice close shave and that blade was durable lasting months. These blades struggle after a month to give a nice smooth shave.

So I went through both in one day. I'm sure this was not intended as a single use item, but the part that holds the foil wad raised up because some of the little pieces of plastic that keep it all together ended up breaking within seconds. See those three little black specks in the photo? Those were rattling around in there and fell put when I took it off the razor. I'm returning it, so.its not a waste of money. I don't know if this is a common problem or what, but it was a total waste of time for me.
