Review on HiGuard LED Dog Collar: USB Rechargeable Glowing Lighted Up Collar for Small Medium Large Dogs - Water-Resistant & Cuttable TPU Safety Collar Lights by Tyler Turner

I was pleasantly surprised by the durability and brightness of this collar. I've tried different types of lighted collars and this one works the best so far. It uses some type of fiber optic material to create a fairly even glow throughout the collar. Cut to length and insert the cut end into the coupler. Just like this one. It has 3 settings: fast flashing, slow flashing or steady glow. I bought a pink collar and it glows very well at night. Compared to collars with LEDs a few centimeters apart, this one shines much brighter. The kit includes a USB adapter for charging the collar. Collar material - durable, flexible fiberglass. Definitely recommend!
