As cool as the northstar may look, it can break easily. Here are some things you need to watch out for.
1- You know how theres arrows aligned on the yoyo ? DONT align them back every again. Why ? It could crack the center of your northstar cap open like it is about to do to me. So I align the arrows back each time and I felt the side cap where the axle is and i felt a bump from the axle. Also I saw that it started to crack. This may not happen to others yet, but it could happen. Im just warning you guys.
2- Be very careful when storing it. Or putting it down. It can crack very easily. Ive noticed there is over 6 small cracks on the side that could turn into serious cracks but they are very minor right now.
