At the outset I want to briefly mention the shipment and customer service. Shipping took with me a little longer. According to retailers, the ball bearings should have 4 days to arrive earlier. In my opinion this is not a reason but deducted a star. Then I'll be right there. The customer service was ask my friendly and could well explain why there may be delays. On the whole, one can as to turn a blind eye. Now the ball bearings per se. In addition one can not say much really. I use this set now has a month and am completely satisfied. The important thing is that at the beginning you do not believe that they are worthless. The ball bearings must be run a good two hours. Go pleasantly, are easy to clean and so as I have seen so far, could keep in the proper handling quite long. If I had not thought of at this price point. Now the reason for the star trigger. I do not know if it's just me, or if that is so common, but the plastic cover on some of my ball bearings were already easily scratched when unpacking. Can you forgive now, but you do not. On the whole, the good definitely ball bearings can be used in many areas of longboarding. Allen who elect ever have fun with it :)
