I am completely happy with these blades, compared to a name brand that costs a lot more. Rated only 4 stars because the packaging is not very good. The blades are a bit hard to remove from the plastic case. The used blades are hard to return to the plastic case. A couple of the new blades somehow got trapped in the compartment where the old blades should go. I solved this by taking all the new blades out, and now I use the case only for disposal of the used blades. The blades are individually wrapped so this is not a safety issue. Even with this frustration I would by these blades again because of the price.
