I have been using them for about 4 years mainly because they are cheap and they are Gillette. I have tried other cheap 3-blade razors from Bic and Wilkinson which were inferior to Gillette. Of course, these are not as good as Gillette with the 5 blades, but they do the job. One razor gives me 3 shaves and then the lubricating strip wears off/deteriorates and it's time to throw it away. Make sure to buy them from a supermarket with a buy one get one free offer, meaning one pack of 6 and another pack of 6 as a gift, all for about €6.50. So with €6.50 (which is 6+6 razors), I get a whole year's worth but I only shave once a week. Now if someone shaves more frequently, it would be good to get 2 packs + 2 as a gift, meaning 4 in total - all together for around €13 for a year. Very economical and quality razors.
