Hi everyone. did not find where to post this, so I will ask here. My coach asked me to look for some info about different table tennis robots. He wants to purchase one or two (have no idea) for our training. And I do not know anything about any of them and what's the difference, so just thought someone could share his experience. I found the list but can't post it, please let me know if you had experience with any. The problem is I also have no idea what's the budget. Will ask him tomorrow and let you know; as I see the price varies from $90 to $650. Not sure he's ready to spend $650 on one machine.
