Good safety product

I have a black dog that escaped our yard when I put him out for his nightly tinkle, I spotted him just as he was running out onto the road and my heart stopped when I heard the squealing of brakes and a thud. Thankfully the thud was a tool box in the back of the pickup truck hitting the cab, he was able to stop just in time. That prompted me to buy this incase he ever escaped the yard again, especially now that it gets dark so early. This collar is light on his neck, easy to cut to the size of his neck and is very bright, we keep it on him at all times and just click it on when we go out. I can now see where he is at all times in our yard. You can click the button for a solid blue light, slow or fast blinking. Easily rechargable so there is no worrying about replacing batteries. Perfect safety product for nightly walks. I personally think it's a must have for any dog.
