The downside? They’re expensive. Like, really expensive, depending on which one you get. Whether you really need one depends on your budget and how you’re going to be using your ball. For example, I use official match balls for practicing freekicks because they fly through the air really nicely. However, I don’t use them for training because if I lose my ball I’ll be set back $100-$300.
This ball is a size 5 which makes it great for small children to play with. Batteries for the lights are included. While they do have a long lifespan, they are easy to replace when the time comes. The LED’s shut off after a minute of inactivity, which helps make the batteries last longer. Your child’s knowledge of cause and effect will increase as they realize the ball lights up after being hit or kicked.
On the other hand, replicas (sometimes called training balls or gliders) are designed to be just like the official match balls but are much cheaper. Their panels are often stitched rather than thermally-bonded and are made of a different material. However, they’re not necessarily less durable than official match balls. So, they’re the recommended option for most players. https://www.youtube.com/watch?v=j2Xn84L3Kcs
