Takes 5 minutes to change the struts. They just pop off
Incredibly simple and easy to reverse - one tip I'd suggest is pre-place the little spring-metal clip that holds them in place on the foot so that you can slide it into place easily once the strut is attached.
Muggins here tried for 10 mins to fit the little swine with the foot in place already before wising up and doing the above. If I'd known that beforehand, it literally is a 5 minute job.
