Review on No Shock Bark Collar for Small and Medium Dogs - Rechargeable, Humane Anti Barking Collar with 4 Color Faceplates, Harmless Prong-Free Design, Sound, Vibration, 7 Sensitivity Levels by Melanee Deal

collar for my girl Cavapoo so I wanted to change the collar to pink. Wish instructions told you how. I finally partially unscrewed the 4 screws on the back of the collar and was able to remove and replace the blue plastic. phew lLucky there were nails! Charged the collar but couldn't get it to work. Finally, read the instructions again and there is a small power button with a circle around it that you can press. I had to use a pen to get it. Once it worked like a charm. Tried turning it off to save battery. The light stays on anyway. The collar is nice and light and it's great that it's pink to distinguish it from boys' collars. It's a great relief to stop a puppy from barking!
