Product Customer Reviews

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.
Sportingly.

Commercial Director for Team Sports
Great ball but pricy
Great texture and good bounce
The weight is off - measured at 564g, whereas the ball is upposed to be in the range of 580g-620g.
Very durable, deep grooves, grippy grip! (And approved by FIBA)
Brilliant outdoor ball for acrylic painted court, my 16 & 17 year old boys loved it... this is actually the second time we bought this ball

Its not a usual size in HK though it is called adult ball
Hi Bert,
Thank you for spending time to write us feedback and I apologize for bringing you this unsatisfying experience.
All of our basketball are manufactured following the spec of the FIBA. In general FIBA basketball is slightly lighter & smaller than NBA basketball because using the different spec. In this case, BT500 Grip Adult Size 7 Basketball is following the spec of the FIBA size 7 to manufactured, so it will be slightly lighter & smaller than the size 7 NBA basketball.
Please let me know if you need any further assistance and do not hesitate contact me at andrew.so@decathlon.com

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 match!
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 clubs) 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 are what you need.
What height basket should you choose?
The official height of a basketball basket is 10 ft. (rim height). If you want a basketball basket for your child, 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, club baskets are set at 8'6". After the age of 10, both girls and boys play with 10' baskets
