The yoyojam speedmaker is a very good yoyo for its price. I had my speedmaker for about 2 weeks now and it works great. Sleep Times for me are around 20-40 Seconds. Caps are removable if you are asking that. The shape of the yoyo is a very nice unique shape. The weight is a good weight for a yoyo.
Take Apart Design: 5/5
Sleep Times: 3/5
