The Velleman kit isn't suitable and an offense against real Pong !!
It uses PUSHBUTTONS for up down movement of the paddles which is of course INSANE because you completely loose the speed factor of a pot that you can move as fast or slow as you want. this takes away 80% of the fun and original game feel.
Further, it looks really awkward. paddles and ball look WAY too thick, it's like playing Pong on a 5 cm. screen.
Everything else looks different too. Also.....the gameplay sucks even more, because it clearly doesnt make a difference if you hit the ball in the middle of the paddle or on the edge, which is very important of course to get different angles.
Look at this video from 19.48....
