Question: What size balls are these????? What size balls are these?????  Why do you so many sellers not put the ball diameters???
Document: Other than the weight and size the balls are pretty much the same (See picture bellow).PerformanceI use the balls mainly for dodge ball bot also when practicing manipulation with the kids (one of the 8 main themes evaluated for phys. ed in my province) that way they can all have material without me fearing them getting hurt.Even tho I use and enjoy them, they are not perfect.
For those wondering, these are 6 inch balls. I prefer a 7 or 8.5 inch ball for adult use, but these are still great. You can really throw these, with just a little sting on impact. During our first practice with these I was hit by our strongest guy "below the waist" and wasn't really affected. Can't say that about the old rubber balls we used. Only  4 stars because they don't list the size.
These balls are a great find. No sting on impact, soft inside, coated outer shell. Have the right weight and design to throw and hit your target. Perfect for playing safe and having fun. Seems pretty durable and well made. Pay attention to the size you want to order or you may get smaller than you want. I ordered the 6&#34; and they are slightly smaller than your average play ground ball. These do not bounce- not made for that.
Just had our first dodge ball game in my after-school sports program, these are very high qaulity dodgeballs and so much fun to play! Great size for all ages and they do not hurt at all, even the huge shots to the face. 5 stars!
Very good quality and packaged very well. Arrived here exactly when they said it would. Good service. I wish the size of the ball was given because they were not the size I expected and that made me a bit disappointed with the seller, but that was not a huge deal and I may have just missed where it was given (if so, it could have been easier to see because I looked diligently for it.) Overall it really was a great buy.
I purchased these 6&#34; balls as a less expensive alternative to the larger 8.25&#34; ones, which can range from $20-$35 each. As an avid dodgeball player, my initial reaction to this set is very positive. The foam is firm and the skin tightly wrapped, exactly what you want to see. As many other reviewers mentioned, the true test will come with how well these hold up after regular use in our league.
This dodgeball set was not what I was expecting from the description. The 6" description obviously is a stretch, even measured by circumfrance. They are more like 3" in diameter. These are clearly kids toys, and not the "official dodgeball used in many leagues". I am not aware of any kids dodgeball leagues, but there are widespread adult leagues which use three sizes of much larger balls. Hello, there was even a movie about adult dodgeball, so I'm not crazy here.
The kids love these size of balls! The colors are great and are easy to spot once thrown in the club.
I loved the dodge balls. They were the size I anticipated and the material they are made out of are safe for the students. I think they are going to work great in my PE gym.
These balls were much smaller than i anticipated. Mostly my fault for not thinking the size was what it was. Just make sure to check the size you need before you order.On the good side. The seller was fast and I had no issues there.
