Mine did, but it was my own fault. Didn't keep it tight in the quick release and the threads stripped. Couldn't get it out of the quick release so I removed both from the bike and tried to extract it manually, broke off the threaded bottom end of the flag into the quick release.
The safeglow whip was very, very bright and I was glad to have it when peels broke down. I may go a different direction, but I still think I will want to get another.
