As I said these draws refills do what is asked and that's the main thing. They clean my shaver like new. The price however does not change too down for years and it's a shame. By cons, to have seen the price of compatible razors recently (2014), I was shocked by the evolution to higher tariff overly points to several hundred dollars to shave! Let Braun, stop a little one-upmanship. A simple razor does the same thing for pennies Euros / month. Delivery and service on top, as is usually the case at Amazon.
