Hello Coach Seta,

Thank you for taking the time to write this review.

I am surprised to hear that the R500 ball popped after only 15 minutes of use,

as this ball features our 'Magic Jam technology' which reduces air loss.

Please feel free to return it to the store of purchase for a refund or to swap it over.

Really good quality ball for the backyard, feels a little heavy, but very sturdy. One of the few balls my dogs can’t wreck.

Kualitas product sangat baik

Mungkin karena saat ini yang belanja online lebih banyak, menyebabkan kecepatan proses packing sampai pengiriman lebih lama. Untuk kualitas product sendiri ga perlu ragu. Pasti kualitas baik. Harga juga menyesuaikan budget

Bola yang bagus untuk dipakai di outdoor. Gripnya enak, bahkan jika bola sudah mulai gundul. Berat bola juga cukup standar untuk dipakai bermain. Dibanding bola karet biasa yang kebanyakan berwana oranye, menurut saya bola ini lebih worth it digunakan.

Grippy And Durable

Have been playing on on cement courts for a while now. The ball has good ridges and grip is good. And does not get punctured. But the weight is a little higher than ordinary balls. Overall the best basketball for cement court use.

What makes the tarmak r500 and its magic jam so special?

The Tarmak R500 basketball is one of a kind. Some balls are slippery, have a terrible bounce and can't be repaired. We wanted to offer a solutionIn addition to its reinforced covering, this ball contains a green gel made of rubber microparticles that get sucked into holes to not only fill, but to also reinforce these areas. This prevents air leaking out so you can keep playing. We called this gel Magic Jam.

Is the r500 really puncture-proof?

The Tarmak R500 ball won't go flat for up to 10 punctures of 2 mm in diameter. If you find a hole, bounce the ball at least 10 times. This causes the Magic Jam to move around and fill in the hole before hardening on contact with air.If the ball ever loses too much pressure, remember to reinflate it (to 0.62 bar for the perfect bounce).

What makes the r500 so grippy?

Having a good grip is essential in basketball.We turned to something else that depends on excellent grip for inspiration: tires.The R500 Tarmak basketball comes with a rubber covering that makes it durable and exceptionally grippy. Its sculpted panels were inspired by how tires are designed. They are alternating and have thick, basketball-specific pebbles to make grasping the ball a doddle.

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.

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 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

Did you know that all tarmak products are tested in the lab and in match conditions?

The design team behind the Tarmak products is based at Kipstadium in Northern France. It constantly aims to make basketball a more enjoyable experience.All Tarmak products have been tested in real-life situations by actual players for a number of weeks. These regular tests, along with customer feedback, help us develop our products.Lab tests are also carried out to check our products' various properties
