Pleased with my first 7 Days blade.Smooth and sharp and 5 excellent shaves from 1 1/2 blade used in several SE razors.
I bought Treet Platinum and Treet Carbons, for me they are one and done. My favorite are Personna Platinums because I get a smooth comfortable 6 day shave but that comes as expensive compared to Treets. Thanks to the Blade Exchange I traded for Treet 7 Day. I got a smooth, comfortable and non irritating 6 day shave comparable to the Personna Platinum.
