Anyone tried the new Ocrevus Zenovo yet?

I get to try the new Ocrevus tomorrow, it's wild that they found a way to make the 5+ hour infusion into a subcutaneous injection that takes no more than 45 minutes for the process to finish (that's with observation too???) Well what has your experience with this been as of yet? Any side effects? Do you still get the pre meds? I'm looking forward to this-
