I was very disappointed with the spinner. I was so anxious to use it and once you have it, there is no where to use it. It would of been great if you could ride it around like epona. And there were only about 2 or 3 places outside Arbiters Ground was where you could use the spinner.
The spinner looked fun at first. You gotta admit, riding that baby in the Arbiters grounds was fun! But after the temple, it was useless and it's only for a one dungeon use.
