Jognee Tennis Trainer Tennis Trainer Set with 3 Rebound Balls, Portable Tennis Equipment, Tennis Ball Practice Trainer, Tennis Trainer Ball with String for Children, Players, Beginners

My daughter loves this!

Horrible I hit the ball TWICE and the string just fell off the ball what a scam! A waste of time. Dont even bother

Only for children or beginners

The first thing to note is that this item is a toy/amusement game for children, not adults - and the product description does actually state 'Age range: kid' and leaves the responsible adult to judge the age suitability for the child in question. Personally i'd suggest it's best for a 5-8 year old and that may even be pushing it a bit.The weight or base needs to be filled with water before use, and herein lies a further clue as to age suitability because it's very small and flimsy. Any adult using a tennis racket to wack the ball is likely to send the whole contraption into orbit. I'd suggest equipping a child user with a small paddle type bat to play with this trainer.A point to note is that the trainer needs to be assembled, in the sense that the line holding the ball is only tucked into the retaining loop on each tennis ball during assembly i.e. do not assume it's all good to go.To conclude, as a young child's trainer it's just okay. I'd like to see a more substantial weight/base than that on offer, because it's inadequate for continued use if a child's skill improves and they are able to really hit the ball with a power shot. Essentially though the item is as described, it's the photos of adult users that are somewhat misleading.

This tennis trainer does not really look man enough to be used for adult use, I tried it out with just one small bat and not my full sized tennis racket and I managed to knock the ball of the elastic and across our green, this might have been down to the elastic, which I have to say being rather thin, not being tied securely to the ball, once I retied it and tried again it worked ok, but I just think with the extra force of a tennis racket the ball will probably come off again if not snap the elastic.Anyway this was more for the grandkids and using small bats they did have a whale of a time hitting the ball and it coming back to them, at one point the cap did come of the base and the water flowed out, I thought I had screwed the cap down tight after I filled it but maybe I didn't.So I think this is more for kids than keen adult tennis players.
