The collars are great, love the multiple settings. Wish they had an actual small though, will never fit my chihuahua, I'll have to check for extra small. Nice for walking at night, feel safer having my lab glowing!
My dog is almost blind. When I let her out at night the collar lets me see where she is at all times. It works great. I bought one last year and now have purchased two more as backup and gifts.
Works great in all modes, but completely adequate for keeping track of the dogs at night. With horseback riding at night, we use flashing lights on us, but the dogs only had reflective collars before, a concern for cars passing. Now they can be seen easily. Would I purchase again? Definitely.
Had the LED illumination collar, you will not to fear that could not find your pet, pet's security gets the protection. The driver will find your pet with the LED light in 150-200 meters, the dog's security is guaranteed, you and your pet will be both safe, and you can find your pet easily!
