Looked at several dog light collars bought this one,great value for money,does what it says on the tin ,you can track the dog movements even in the pitch black and the battery once charged lasts a long time.Thank You.Great just about the best light collar I've brought for my dogLights up well but switch is a bit dodgy.Kann ich nur weiterempfehlen, ist schon unser drittes, hält lange, sehr gut sichtbar, und mein Hund kann sich und andere nicht verletzen beim spielenNo way I can lose my black dog in a dark field when he's wearing this! It's waterproof in rain and long wet grass. keep it hooked near the door and it just slips on over his head, no buckles to hold up the night time walk.
