Power Pong Delta vs Omega

• The Power Pong Delta is very similar to the Power Pong Omega, just without the ability to be controlled by the Power Pong app via Bluetooth technology. If you're happy to control your table tennis robot using a physical control box (rather than your phone/tablet) then the Power Pong Omega is a great choice!
  • It has a lot more memory space for storing drills than the Power Pong Alpha and can also create 8-ball drills. It will also enable you to create clusters of drills so that you can plan out your entire training session.
  • The user-friendly control panel with the touch of a button makes it easy to increase or decrease the amount of speed, spin, and height of each shot and to set up combination drills suitable for both novice and high-level players.
