That's sweet, dude. You're going to enjoy that razor. It's a good one.
When trying blades from the sampler, give the first one you choose multiple uses as it won't be the same for each shave. You want to be able to develop an educated opinion on each blade so you can rate them fairly and choose your favorite. Some need an initial shave to smoothen out. If it's absolutely terrible from jump street, go ahead an pitch it. You might want to revisit the ones you dislike as poor initial shaves could be the result of poor technique while you're getting the hang of it.
