These are expensive, but buying knock-offs has proved to be more expensive. Finally got around to purchasing these.

It was well packaged to be protected for shipment damage in transit. The blades hold up nicely, and because i only use them for my mustache and to trim up my hair cut, a single blade lasts me about six months.

The performance of these replacement blades is truly exceptional. Easy to replace and install. First blade has been doing well for over 4 months.

They make the blades purposely wear out within about 2-3 weeks, once it wears it is 100% not the same shave. I'd rather use a gillette hand held disposable.

Some of the packaging is paper and recyclable. The rest is not nor is it indicated to be comprised of any percentage of post-consumer materials.
