Review (4/5): As expected.
The blades I received were of the same quality as the original that came with the razor.
I did have an issue with the original set of blades. I attempted to cut a six days growth beard. Multiple hairs caused the blades to bend, so that they would spin into the blade guard/cover and cause the motor lock up.
I hope I don't hit my side burns one day and do the same thing.
