Review (1/5): These heads were terrible. They had a problem engaging with the stalks ...
These heads were terrible. They had a problem engaging with the stalks that turn them. They made a clicking noise as the stalks turned, but the heads did not. Once they did engage, the shaving experience was terrible. They pulled the whiskers, and left my face hurting and still had whiskers. Don't waste your money on these, buy genuine heads.
