Some questions about razorock mj90A

I just bought a mj90A from Italian barber, but the box is printed with mj90 without A, and there is a white A on the plate. I have heard about the old version of MJ90 and the new version of MJ90A before. Did I buy the old version? Is there any difference between them?

This is the new version, I believe. I have the original version. In the original version, there was also a milder plate included. The handle was also titanium.

I believe RR deemed the milder plate to be too mild. But I love it. YMMV.

So the reason I think you have the current offering is that the MJ90 is only offered with the A plate now.

This is my understanding.

That’s also my understanding.

Thanks for your reply, I saw some plates are not printed with any letters, so I am confused
