I have been using Astra Superior Platinum for quite a few years now and they have been my "go to" blades despite trying others. I'm not sure if it is my imagination or not but I've found the Astra SP not to be at the same quality as they were about 7 years ago. I'm finding them to be less smooth and don't last as many shaves as they used to. Although fairly sharp, I found they dull out far sooner than I like. I still like them although I wanted to find something else that was as sharp yet smoother and last a little longer. I did some online research and based on some positive reviews I went for a single pack of the Tiger blades just to trial. This was paired with my Muhle R106 as well as some of my vintage Gillettes - nice and smooth yet efficient. I also tried it with a recently purchased Razorock German 37 Slant - perfect! I have really heavy coarse facial hair and really sensitive skin. The finest shaves I've had in a very long time, with no nicks nor any irritation, especially when paired with the Razorock German 37 (purchased from Fineshave). The blade has kept it's efficiency over 3 - 4 shaves and I haven't found any tugging so far. I haven't had these for very long to fully apraise the longevity and results may be different for others (different skin types, razors and shaving technique) but I've since ordered a bulk quantity to have on hand and I will likely reach for these first before using up my reserves of Astra SP blades. I did say these are early days and my opinion could change but so far I'm quite impressed. Considering the price vs performance ratio, I think Tiger Platinum blades are an excellent deal.
