For spin ok, but for markers it's nothing!

For the price you can expect unfortunately nothing ....
Have 4 * 500 ordered and have to say the delivery was "perfect" no burst Balls. Color was here damn me. ;)
Unfortunately I had the problem that most Balls are already burst in your hand, if you have not been paying attention because I play with a slingshot is a clear disadvantage for it. Since the balls have different strengths can they not use the markers, as this otherwise bonded by the color so that no more balls come out of the barrel.

Conclusion:
Who wants to have with his spinning fun with pals who makes a good choice to start with. But if you reach for markers, you should already spend a little more money and tend to higher-quality balls. ;)
