Welcome to the forum Smarte. Slow and steady wins the SR race. Just use it on your cheeks to begin with. Finish with your DE. As you get used to using the SR and your confidence grows, move onto the neck, then later to the chin etc. Once you get the hang of it, you'll be glad you stuck it out. You have a great razor in that King Cutter. Read everything you can, watch every video you can find. Practice your stropping. Good luck.
