Are magnetic eyelashes reusable multiple times?

A lot of packaging says magnetic eyelashes are reusable, but I’ve seen wildly different claims about how long they actually stay in good shape. Some people say they get tons of uses, others mention the magnets weakening or the band losing shape pretty quickly, so it feels like proper care probably makes a big difference.

I’m thinking about switching because traditional glue lashes irritate my eyes sometimes, and I like the idea of something quicker to apply. The only thing holding me back is not knowing if they’ll really last or if I’ll end up replacing them often anyway.

For those who wear them regularly, how many uses do you typically get before they stop performing well?
Any care tips that helped extend their lifespan?
