It attaches easily via mounting hole on my rear rack, which means it frees up room on my seat post for my bag. It also supposedly lasts for 100 hrs. in blink mode with 2 AAA batteries. The thing is pretty darn bright. However, I don't always turn it on when I tour. I will only use it if light/weather conditions seem to warrant it, like in fog or darker conditions caused by a storm. (I do use it regularly when I commute/ride in the city in the dark.) I recently got some Watson rechargeable NiMH batteries, so that's what I use in the light.
This is a good idea. I'll bet it runs longer than the planet bike superflash turbo on batteries. I may use this for daytime riding and save the superflash turbo for low light conditions or the sun is low on the horizon.
