The magnet detached from the plastic on the first use😭

I like these little magnets but it's hard to trust they'll stay on. I've yet to have been able to use these for a race, but testing on my own shows they work. So far, they stay on, but I am having trouble fully trusting they'll keep a tag on for an entire race (depending on placement).

I've heard of these, and when I saw them on Amazon, I had to give them a try. I hate to use pins on my running shirts, and this avoids that mess.I am not fond of the "My Race My Pace" and logo on the pins. So, I simply installed them with that part on the inside of my shirt and the round, white backing on the outside of my shirt. Perfect! Note that the side with the words and logo is oval, but the backing that I had on the outside of my shirt is smaller and perfectly round.The magnets are quite strong, and I had zero concern that my bib would fall off or that the magnets would somehow come loose during the run. Everything held up great.The current price of $7.49 seems very fair, too. I have no complaints here, and I think these deserve 5 stars. My daughters liked them so well that now they are asking for them. I guess I'll have to buy them some.
