Query: Reliable mechanism, but not durable

I've gone through quite a supply of breakaway collars for my cats, so I've had a chance to practically evaluate several major brands, this one included. This collar features a broad ovoid tab as the latching mechanism, and it's just hands above the snap latches on other collars. Unfortunately, the reflective material, which to me is as much a safety requirement at a reliable latch, quickly faded and the adhesive holding the reflective fabric fails, rendering the nice and otherwise durable collar ineffective within a few months. When new, the reflective material was easily bright enough to spot a kitty in the dark at a 100 yards with a single bulb AA LED flashlight, so no problem being visible in car headlights. Without the same reflective material, the cat is invisible under the same conditions. The snug latch releases easily when torqued from the side as it would when caught on a passing object or brush. This would be a 5 star review if the product were durable.
