"I run with my dog at 5 am in the woods, and needed a light for her, in case she darted off after an animal. The product does exactly what it says, and throws off a great deal of light. I like how you can angle it downwards, that's a plus. However, for me, it is VERY dark where I go, and I found that this device was so bright, that my eyes wouldn't adjust to the dark, and I was having a hard time seeing.
There are 3 lights, and 3 batteries, I wish I could just light one light or two. For some reason, I would also prefer the unit to blink. A red or blue light filter would be a nice option, I'm thinking of covering the lens with red tape to see if I can tone it down a bit.
Also, this is not a small device. I have a very large Rotty, and it's fine for her, but I cannot imagine using something this size on a small dog!"
