Not wanting to spend a whole lot of money on the off chance that I would only like one type of blade, this 5 brand sampler pack was perfect. So far, the Crystal blades are the only ones I don't like, but I only used one of them. The Derby, Astra, and Personna Reds are all terrific blades. I've used several of the Derby and Astra blades, and I need to use a couple more Personnas to verify that I like them best so far - nice and sharp, yet smooth. I'm 48, but I've only been DE shaving for a couple of months now, and haven't worked up the nerve to try a Feather blade yet!!
