This LED dog collar is magnificent! It is super bright when turned on, has two different modes, single light or flashing, and is really super sturdy. I love that I can recharge the internal batter with solar while my dog is wearing it, or baring that, I can charge it in the house with the USB. It has been great being able to see her at night when I let her out, and super nice while we are walking at n ight so that cars can see us! I would most definitely reccomend this to anyone who is worrying about the safety of their beloved fur baby!
