Not much you can say about this other than it is a very good "incrediball" type ball. It feels heavy compared to a regular junior cricket ball but I weighed it and it comes in at 4.75oz, ie spot on.
The ball feels like it will last so no worries about hitting it and it splitting. Beware that it is still fairly hard so if you are intending to use this against relative novices you will be better starting off with a wind ball and moving up to this. The advantage this has is that it is softer so easier on the hands but it still hurts.
Overall a great product for junior cricket drills, recommended.
