Not really good for training. We tried to adjust the length and speed, it worked OK but it's not consistent. i'm not returning it because my son thinks it's fun. So, if you use it as a toy or just to spend time, it's nice. Otherwise, if you want to have it for training, i believe you need to look for a better one.
