Yeah, I have a SuperSpot. It's good for a small flashlight (although underpowered compared to a Fenix or something) but pretty useless on a bike. Sometimes I'll strap it to my helmet as a blinking "be seen" light, but that's about the most I'd use it for.
I'm interested in the 2W blaze, but it would be as a back up to my back up to a Magicshine or as another "be seen" light.
