Review on 🐾 Furhaven Pet: Hands-Free Bungee Dog Leash, LED Collar, Leash Extender, and More - Active Dogs and Cats - Multiple Colors, Styles, & Sizes by Chrissy Ramirez

It is not rechargeable but the batteries are not easy to replace. Nowhere on the packaging is the required battery size indicated. That's 2032 by the way. For the red extension: Aside from that serious little inconvenience with batteries, the purpose of the light is to warn drivers etc that the dog is walking. It's great there. The light is noticeable at night and a couple of my neighbors have commented on this. A flashlight is a must at night. That doesn't enlighten anyone if that's what you're looking for. For Rosa: It's not an extension, it's a collar. It doesn't glow quite red, and there's no way to turn it into an extension. Additionally, there is no way to return or replace the ones I have received on the order summary or anywhere else that I have checked. I'm so sick of Revain and the platform loves to support modern carpet packaging.
