the1521S has a carbon fiber shaft and a power load system for installing new string with the push of a button

The 1502SF has an aluminum shaft and a rapid load system for installing new string quickly and easily although it requires manual turning of the head to wind the string.  Still pretty simple but not quite push button.

Both 15" and brushless motors
