Cute Heart Flashing LED Pet Collar Pendant Light - Red (2*AG13)

Pros: Bought this for my dog to use on night time walks. She is jet black and nearly impossible to see when there are no street lights around. Having a blinking light does help to quickly locate her when she runs under trees, bushes and such. I've only had it for two weeks, but it seems the batteries should last a while.

Cons: The major con with this tag is that the blinking light is only on one side. Often the tag will sit against my dogs fur and the blinking light will be much less noticeable. Also, it's just a single LED so it's not terribly bright and may not be noticed by drivers of cars, but anyone riding a bike or walking should notice it. It is bright enough that I can see it across a soccer field at a nearby park if I look for it.

Other: A pretty cheap device that will help you locate your dog when it's dark outside. Would be nice if it had LED's on both sides and if the LED was a bit brighter.
