These new razor heads were hopeless and a complete waste of money. I got the sh50 blades but the blades don't mesh with the machine heads properly. Their seems to a design change. Should ask for my money back.
Fast delivery, works well, has enough output for several pedals, I'm very pleased, thank you.
