Review on HiGuard USB Rechargeable LED Necklace: Illuminate Your Safety and Style at Parties, Concerts, Birthdays, and Outdoors! by Chris Perez

I bought green and pink collars for my dogs as I live in a large area off the road so my dogs are usually off leash. Now I can see them clearly at night, even at a distance of several hundred meters. Collars charge in a short time, they are colorful and bright, have 3 different lighting modes (including slow and fast flashing). You can easily cut the collar to the desired length with a pair of strong scissors. I can't say anything about the durability and battery life as I just received it today. The instructions say NOT to use a fast/high voltage charger as this can damage the battery so I used a standard 6V cell phone charger and had no problems. I recommend!
