Good ball but color mismatch

I like the ball, unusually grippy, but that's a pretty good thing. But I expected to get a brown ball and I got black.

Dear Kevin,

thank you for your message and your positive comments about the quality of this ball.

We are sorry about the mismatch color.

Best regards

Ball is Gripy

Ball leather feels good initially, however it's very sticky when dribbling the ball.

Hello Raymond,

Thank you for taking the time to write this review.

Apologies for a late response. We have been slowly clearing up our backlog but I would like to assure you that we will be answering all our customer issues.

I am sorry to hear that you were not 100% happy with the BT500 X Grip basketball. It is designed to have more grip than a normal basketball. Hopefully the more you used it, the less sticky it became for you.

A good quality ball at a good price.

A well-balanced synthetic ball. Good for both indoor and outdoor courts. Very grippy, great bounce and great feel to it. A good ball for causal game and practice.

How much should you inflate your basketball?

A basketball that is overinflated or underinflated doesn't give you the best match experience. The recommended pressure is clearly marked on the ball by the manufacturer. Ideally, you should use a pump with a pressure gauge so that you can be more precise. At Tarmak, we recommend a pressure of 0.62 bars. Enjoy your game!

What ball size to choose

The ball size depends on the player's age and sex. Size 1: From ages 2 and up Size 3 to size 5: Girls or boys ages 4 to 6 / Baby basket under 7 age group (depending on levels and teams) Size 5: Boys and girls ages 7 to 10 / Under 9 and under 11 age groups Size 6: Boys ages 11 and 12 / Under 13 age group Size 6: Girls - Women of all ages over 11 Size 7: Boys - Men of all ages over 13

What ball should you use?

If you want a very durable ball, go for a rubber ball. If you want a ball with a good feel, leather or synthetic is what you need.

What height basket should you choose?

The official height of a basketball basket is 10' (rim height). If you want a basketball basket for your kid, you need something that will grow with them. For younger kids, there isn't an official height, so you can choose whatever suits them best. Up to the age of 10, team baskets are set at 8'6". After the age of 10, both girls and boys play with 10' baskets
