We got this collar because our dog was an expert at unbuckling collars, she'd either slip out of them or scratch at the buckle till it opened. This sucker stays on, doesn't loosen and the clip is always at the top due to the weight of the buckle. The peace of mind alone was worth it. You do need to oil/clean the buckle after a wet/sandy/snowy/otherwise gritty experience though. But it has held up well for over a year.
