I have been using Astra Superior Platinum ever since I first started eighteen months ago. Monday I loaded my first dud I have ever used from that line. The mistake I made was thinking that it was because I pulled the fifties model Flare Tip (made in England) yes that is right only two of these I have ever heard of and I have one, I had not used it in a while. Looks just like a flare tip but says made in England kind of crazy, but it shaves as good as my other three Rockets? Any way I made a big mistake of using it a second time. This pack was from a friend that I bought something from. I have broke open a new one hundred pack and the Rocket to find out more. Everyone makes a lemon every now and then. In the mean time I have the worst burn I have ever had.
