These excellent blades last me about 4 shaves. I find them to be sharp and still comfortable. My whiskers are moderately course. Works in all my razors.

Works OK but I’ve tried better. I have a medium to light stubble, and even after three passes, it still seems to leave more stubble than I’m used to.

Hi, forgot to mention that the GSB works in all the razors in my rotation which are a Gillette Slim Adjustable, a Gillette Super Speed Red Tip, and a Gillette Super Speed Flare Tip. Very, very consistent from razor to razor as well as blade to blade.

Best blade for my face I have found so far. Prior to finally trying the GSB, Astra Green and Persona Platinum would pretty much neck and neck on which one I like shaving with best (basically, whichever one I was shaving with felt the best lol). However, when i first tried the GSB, it was love at first shave. It was sharp, plenty sharp, but smooth, the smoothest blade I had used yet. BBS shave after BBS shave and only two lathers (instead of 3 lathers) to get BBS. The Gillette Silver Blue is a game changer for me as it is by far the best blade for my face I have found to this date. Highly recommend you give them a try as while YMMV, it is worth it to find out if the GSB works for you.
