We found it interesting. Our surgeon ( unused ATM) publishes real time side effect data ( he is considered a top surgeon)

This is also interesting to us but we did wish the dark green zone info was more transparent ...tablets or no tablets and 'sufficient for sexual intercourse' being compared with prior to procedure ( 70% strength for example)
I do like as much info as possible before making a decision but I have learnt on here that we are all very different..
Good luck
