I LOVE THIS! I have a black dog that I cannot see well at night, especially when he is off his leash. I used it for the first time last night and I had no problem seeing where he was. It came charged, but I went ahead and charged it since I did not know how much of a charge it had. I bought two! That way I can charge one and use the other. I do not know how well it works to use the ring to connect the leash to. I strictly bought the collar for visibility and use a vest to hook the leash to. I can definitely recommend the collar!
