It's been several years since I use it and it is still like new. No proof, no trace of wear, nothing. At this rate, I'll be long dead when it is good for the trash (or rather recycle as it is metal). Easy to install, use and maintain, it is very efficient. It has nothing to envy to 5 razors blades brands. Despite a thick and hard hair, I am equally shaved a fraction stroke (10 100 blades and blade week, there is no photo). With a brush and a shaving soap, it is clean shaven at a cost very competitive. Each family member has one and they are all happy. Even my wife uses it pleased (the razor does not slip even soapy hands well). This type of razor is not reserved only to men (notice the ladies who would be interested). In summary, I will not come back for anything these shoddy overpriced razors that offer major brands.
