Product Customer Reviews

It was a gift for my son, who loved it.
Good product and good grip
Great product
Quick drying and not afraid of water
Perfect!
The feeling of touching the ball is relatively sticky, but after getting used to it, there is very little slippery phenomenon. The deep groove also strengthens the grip. It is cost-effective, and it is highly recommended as a ball for playing indoors.
Great 👍
It's a pity that consumers are not told about the difference between bt900 and 900x
Good product
I am happy to have visited your store.
Suggestions can increase the sense of color design
Excellent and son been playing since bought.
Good ball the rebound is correct, on the other hand small flat on the touch. I have the impression that from the moment the ground is a little dusty you easily lose grip. This requires us to clean it regularly. Another thing, I find this ball slightly light compared to the ball of my amazing club for an official FIBA product. Unless it's the new norm now in terms of weight.
My son won't take it out of his hands anymore ;-)
Way better than moltens lol

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 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 groupsSize 6: Boys ages 11 and 12 / Under 13 age groupSize 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.
