Good Quality

The deep texture of the groove is soft and the hand feels good. It is really good for indoor venues and clean concrete courts .

Very good quality and hand feel

Rather than getting a fake molten from other ecomm platform I urge basketball lovers to get this as it's really good quality and at a very affordable price range

Hello Sin Yew,

Thank you so much for your review to us. We're sorry that the BT900 Size 7 Basketball FIBA-approved you purchased didn't meet your expectations.

We suspect that the product could have been old stock that has been stored in less than desired conditions, or could have been tried on by other customers in the store. Rest assured that we do place emphasis on taking user feedback to improve on our product quality.

Nevertheless, you can actually bring the basketball to any experience store (i.e. Singapore Lab, Orchard, Joo Koon, City Square Mall or Bedok), and one of our teammates from the Teamsports department will be able to inspect the ball further, to investigate on the possible cause.

Thank you for shopping with us and I wish you a pleasant week ahead :)

Sport on safely!

Old stock with poor stitching (glue)

Good quality overall for the price, but the product obtained was manufactured a year and a half ago. The glue at connectors are coming off and the sticthing is in pretty bad condition. Would love to take photo to show but they dont allow picture insertion Would recommend seeing the product physically before purchase (and check the manufactured date as well)


Hi Kantitat,

Thank you for taking the time to review our products. I am sorry to hear about your less than satisfactory experience with this BT900 Size 7 Basketball. 

We suspect that the basketball you received might have been older stock as what you have mentioned, or that the ball has been tested by other customers in store. This is because all our products are on display on the shelves, and our customers are allowed to test them before buying in store.

At Decathlon, we strive to offer the most affordable sports products without compromising on quality. Hence, please be rest assured that we do quality checks on the products before packing/delivering them. In this situation, it might be an oversight from our e-commerce team, and I sincerely apologise for it.

We will be in touch with you shortly to help resolve this issue as soon as possible.

Thank you and have a pleasant weekend ahead :)

Sport on safely!

Takes time to break in

To those of you who are looking to buy a new ball, i would really recommend this. This ball when first bought fresh wouldn't be the best ball for games. It takes quite sometime for this ball to be break in, so do be take into consideration. After the break in process has been completed, the ball will start to feel like a $50 dollar mid premium ball, which was why i recommended it. decathlon, if you read this, do make a version like the gg7x,

For a good bounce, 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 bar.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 upSize 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 groupsSize 6: Boys ages 11 and 12 / Under 13 age groupSize 6: Girls - Women of all ages over 11Size 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 3.05m (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 2.60m.After the age of 10, both girls and boys play with 3.05m baskets.
