bought these for our outdoor pickleball court, we put in the mats rather than pain on the concrete and these balls reduce the dead spots where there is a few imperfections. they are quiet so it also does not bother the neighbors.

For those who have not taken their kids through the standard tennis progression, this foam balls are designed for very young kids under the age of 8. The foam ball is much lighter than a regular tennis ball (32 grams vs about 58 grams of a standard tennis ball), and quite a big larger (I measured 90 mm in diameter, vs 65 to 68 mm of a standard tennis ball). The benefit of this ball is that it flies slower, bounces lower, and would not hurt a child if they are hit with the ball.I recently found an alternative use for these balls. I use them to practice pickleball volleys against a backboard at a tennis court. Unlike with real pickleballs which are really loud when they bounce off the hitting wall, these are practically noiseless. While their weight is a little heavier than of a standard pickleball, it is not by much (32 grams vs 26 grams). Difference in diameter is also not a big deal for the purpose of volleying. Likewise, you can practice against the garage door or in the house without the risk of breaking something or disturbing your family members with noise.Since it is foam, they will wear out over the time, but on the other hand, they will not lose pressure and will not go dead after 1-2 months of storage as yellow pressurized tennis balls. As it is foam, it does not like wet weather.

My husband bought these for my son. Great for a twk year old. They are much bigger than regular tennis balls and much softer. They are soft and bouncy and the great thing is I dont fear him breaking anything in the house because they are so squishy. They are great for playing tennis with too which is what dad and him use it for. He once threw the ball at me while playing catch and it hit me on the face by mistake and it didn't hurt. Thats how soft it is.

Bought for tennis, but now use them for various activities! They seem to wear and obvious get dirty a bit on the tennis court.Overall Very Good. Would Buy Again.Light-Moderate Windy Days will slightly effect the toss.4/5 due to higher cost, and only look new for the first hour.

These are the perfect balls for mini tennis or backyard tennis on a patio or sport court. Of course they can be used on a real tennis court in a smaller area for younger kids. Only warning, though -- our dog loves them even more than my kids do! Although it does inspire a game of keep away because if anyone misses a shot, they have to race the dog to the ball. The dog usually wins. If you don't get it away in time they are easily destroyed by a dog. They are still great balls and were never intended to be dog toys, anyway. Have fun!
