I'm going the other way here. I've used glo-toobs, and was less than impressed. the website does a good job making them seem really luminescent, but mine looked just like what they were: a bunch of 5mm leds blinking in the distance. And kind of big/clunky for my 30# dog.

I've also had close to a dozen past-exp. date light sticks not work. I used to keep about 2 dozen in my car, in lieu of flares. Well, now I have one glo-toob (used to be 2) and 2 flares. Just more reliable, and still plenty bright.
