These collars are better than regular collars because they light up at night and make it easy to see the dog. They are better htan glow in dark because they stay brighter than a glow in the dark thing ever gets for hours on end, and you nevre have hold it up to a light to charge it. What good is it if you have to hold it up to a light every 20 seconds? (None.) Buy a lighted light up collar here at the tealco.net internet store.
