ML10 Pro Cup Ultralight is a very good kids/junior racket. Beginners can also use it but it is more meant to be for kids. The weight of 290-315 grams makes it easy for kids/juniors to handle the racket and have a great feeling of the game from the very first shot.
The racket is made with a big sweet spot and has plenty of power that makes it much easier for kids/juniors to get the rallies going.
The handle is smaller than normal to fit the kids’ hands. The racket face is the same size as adult versions, but the ultralight weight makes the big difference.
