Hi there. I just fixed mine: Removed the cloth (the top plastic cover can just be screwed off), then removed the second plastic covering unscrewing a simple screw. Then I was able to reach for the string. Tied it to a new lace where it was broken, slid the lace through the pipe and voilĂ ! Hope you can fix yours. They make it way too cheap for all the people to just buy a new one. Fixing makes you proud though!
