I bought two collars, one for each of two dogs, so that they would be more visible to me and others when off leash. I like the look and the fit, and the light and reflection work well. My complaint when I first put these colors onto the dogs was that I could not get out the crease where they were folded in the packaging. I tried flattening them under a heavy book and buckling them inside out, but the bend never came out. I also thought they were missing a ring for tags, since the only ring is at the top of the neck, but since then I’ve decided that these are not actually meant for a dog to wear continually, since they lasted only a couple of weeks before the plastic covering the light started breaking apart. They weren’t being hard-used, so I have to think that it is a material flaw. I can’t recommend this item.
