Bright color easy to see but not a great bounce on the outdoor court
Style: 6 - Pack, Color: Pink
I liked the fact that these balls were a bright color and easy to see but the bounce on them was not as good as other name brands. They were OK as a back-up and performed better outside then on the indoor courts which are made of a different surface. We are using them , but would most likely not repurchase.

Price was best I found for quantity anywhere
Style: 6 - Pack, Color: Purple
I am a beginner and by no means an expert, but these balls appear to be as any other. The couple at the next court had a Franklin ball that came our way, and I bounced it and popped it back - I couldn't tell any difference in that instance. Sports stores had just one color - yellow (maybe one had chartreuse) amazon has single colors multiple - I thought it was worth this purchase. The purple may be harder to see on cloudy days - as I had on sunglasses and I could see it, but the fence at the court has a "privacy" net, it kinda bleneded in for a very brief moment until the sound was heard of the return, then no problem.

Great Balls!
Style: 6 - Pack, Color: Purple
Great Outdoor balls. These are correct weight at 0.85oz and with 40 holes for outdoor play, not indoor as some other reviewers claim.

NOT Outdoor balls.
Style: 6 - Pack, Color: White
NOT outdoor. Don't waste your time if you are looking for proper outdoor balls, these are indoor. I don't play indoor so couldn't use them.
