Remote Training- to do or not to do?

Has anyone used the remote training offered by companies and do you feel it is practical/sufficient in your opinion for training staff in instances where we would normally utilise on face to face i.e. train the trainer

Dilemma precipitated by an inability to bring trainers on site due to Covid restrictions.

I would be interested to hear what everyone is doing to ensure training for staff, and would you rely on remote training for high risk devices!
