This has a nice bright light that is easily seen at night. The snap ring is located right at the center of the light band opposite the buckle. The buckle naturally settles to the bottom, putting the light band over the back of the neck, almost perfectly equal onto either side of the neck so that the light is visible on both sides of the dog. The light pattern varies from solid to a few flashing patterns and it is very bright.
I really like the recharging feature. Unlike my other collar, I don't need to worry that this will die suddenly one night as I can keep the battery charged. It uses a standard micro USB plug and includes a charging cable but I used one I already have for my phone with no problems. The cover is a bit tricky. There is a small tab on one end that I mistakened for a pull tab. This is the end that keeps the tab attached to the collar. I broke this end off and although I can get the tab back on, I wish it was still connected to make sure I don't lose it.
This is made with better materials and construction than my other standard battery collar. I like this a lot. I really wish I hadn't broken off that tab. This is a great collar and a great safety device for you dog. I even use this in my house when guest are over so they can see my dog at night.
