Hi Jeffrey, I’ve not played on a butterfly amicus prime robot myself but I’ve seen he adverts and I’m sure the quality is good. What I would say is that a robot will never be a replacement for a “Real” human practice partner, just because its hard even for a high quality robot to replicate well how the ball reacts and travels over the table. That’s not to say there aren’t some great uses for a robot, such as getting the same ball in the same spot every time to really focus on getting the technique and movement of your shots right.
Maybe someone else on the academy has tried this robot anyway and can tell you what they think about it or make a quick review as you said Jeffrey!
