When I first started playing table tennis, I bought the basic Practice Partner 100. A good entry level robot which is not that expensive. But it had a very limited range of spins and drills. I wanted a robot which was able to replicate more realistic spins and sequences of balls. It took a while to decide on which robot to buy. I went on table tennis forums and decided in the end that the Butterfly Amicus Professional was the one that would do virtually everything I wanted. I have had the robot for a few months now. Here’s my ‘for’ and ‘against’ appraisal.
