Update by user Jun 27, 2021 Since it's been a while, I've given up on DoggyKingdom. Original review posted by user Jun 25, 2021 I bought 2 dog collars with an led light inside .Collars would not stay on- every time you adjusted them they'd slide loose. The only way I could keep them on was to knot the ends of the collars.The fabric of the collars were worn within 3 weeks and the led light slipped out and was lost. I was denied a refund even when I sent a video they requested. I was offered a discount on next purchase instead. User's recommendation: DO NOT BUY FROM DOGGYKINGDOM!!
