Good blades for daily shaving. Strip and micro-comb work. The glide is excellent, as long as the new cassette does not twitch too much. Problem areas (dimple on the chin) pass at a time. When released in St. Petersburg, the quality was excellent. Let's see how the ones made in China behave. I don't know what caused it, but the prices for cassettes, in my opinion, are somewhat overstated.
