I know that this isn’t the most recommended yo, however it is incredibly durable, no pieces to lose, and no response to mess with. The response is able to be adjusted slightly and can do so much. Now this isn’t going to be as unresponsive as the yoyo’s mentioned in the previous posts so if your kids stick with it you’ll be looking at upgrading. The fact is though, if they stick with it you will be buying more yoyos anyway. Thats how the yo spins!
I use these often to teach beginning players. I’ve seen them bounce off of the ground, cement, stairs, walls, and be just fine. Kids love to take things apart and I’ve seen the bearings or axles lost simply by dropping them in the grass, when using other yoyos. Not the spinstar though!
I really like introducing yoyoing to kids with this yoyo as it doesn’t cost much money and it doesn’t cost me all the headaches of replacing bearings, axles, and the time to dry the tears.
I just thought I’d throw out a different perspective.
No matter what you choose make it fun and good luck! (Parent getting kids involved, LOVE IT.)
