These have stayed locked and in place w/o budging for several weeks!
I wanted a pair of low maintenance earrings that I could put in and forget about for several weeks for an extended trip. The triangle shape caught my eye and was in-stock. They arrived quickly. Yes, they're dainty, but they're just enough to provide a little low profile shine to your ear lobes, and there's nothing on them to snag or get caught in anything.<br /><br />When first putting them on, they locked into place with an audible click. I immediately loved that there's no back post sticking out - you can 100% sleep in these without even knowing they're there. This makes jewelry incredibly effortless in situations where you need to shave as much time as possible off of your morning routine. They're comfortable - so much so that I've had zero inclination to take them out or swap them for something else as per my usual daily jewelry routine.<br /><br />I've been wearing these for several weeks now and they haven't budged despite sleeping and living in them 24/7. I couldn't be more pleased with my purchase, and after the performance test I've given them, I'd happily replace them should one fail.
