I bought this for my son Diabolo. He is a very enthusiastic player. He has the Diabolo now about half a year and it has all the crashes unscathed from a great height. The first Diabolo game unfortunately had an aluminum rod a sharp edge, so that the cord ripped all the time. The seller said that he had such a complaint until einaml. He had converted us the rod. The second pair of aluminum bars was fine. My son had previously a simple (cheap) Diabolo game and find that the new Diabolo worlds better. It runs better on the cord. A very nice Diabolo, which unfortunately is quite expensive.
