Those are great razors and will last you a lifetime. Remember to loosen the doors before you adjust the setting, or eventually you will break it. I started using the slim adjustable as my first razor many many moons ago and I still have it today.

There are many vendors on line that sell blade sampler's as well and they can make a huge difference in your shave when you find one that suits you. Blades are a very peculiar and personal choice in the DE's.

Enjoy yourself.
