The Diabolo is, as it is written in the description, suitable for beginners as well as professionals. Diabolo is absolutely no single children's toys! Some tricks require a lot of skill, which you can train as an adult, and the pellet 20 feet or more to throw into the air, is usually the privilege of the elderly. Definitely a quality product to be even after numerous impacts from maybe 20 meters on asphalt, although scratches (certainly not be avoided), but takes no breaks or shake the materials. There are, as has been criticized in the review of "Balu", the problem that the tape tears in a short time. This is not to be influenced by the style of play. Although I was surprised at first and a little upset, but you just have to once again tie the cord. Here go about 2 cm per side lost. Possibly one can equal to order a second string.
Conclusion: Despite sometimes tearing a string, in my opinion, a quality product.
