Switched from the springs to the magnets at the end of 2025. I put magnets on one carrier and kept the spring on the other to compare. The spring didn’t last one guide. I could tell the difference immediately. Luxury purchase? Maybe. But, if the little hiccups of springs bug your OCD, then this may be the cure.
