I just tried my first Astra DE blade.
WOW!!!!
It is sharp, smooth and very inexpensive. I had a very close and comfortable shave.
I have SHARK, and DORCO blades . Before I throw them out, PM me. I will mail them to you ( I am in the USA). When you get them, mail me the postage ( or offer to buy me a drink next time I am in your area).
How can you lose?
