Im using tesco's own DE blades in a gillette tech, ive never tried any others to compare, anyone every tried tesco's if not what blades do you use?
The Red Personna are my all-time favourite and use these most of the times when shaving with a DE. Once in a while I also like using Shark Super Chrome and Bolzano Superinox Inossidabile, both reliable and consistent blades for me.
