When I first started reading about ProstaVive, I tried to hold off on forming a strong opinion. Early impressions can be misleading, so I gave myself time to look at a few different sources. What I appreciated was the calmer tone in the better write-ups, which focused on information rather than pressure. I still consider myself in the learning stage, and I think that is a healthy place to be. Forming a view slowly tends to lead to better decisions.
