Most of those that read the post yesterday and commented were on the right path. I loved the different directions that people took - especially Tony's idea of the device being a security system. The product in question is called the Flashbak. The picture below is a GIF from their web site. I will be taking some pictures and commenting on my experiences sometime soon.
I guess my first comment is that I am kind of intimidated by the thing. When I reviewed the Bike Brightz product, it took me like 2 minutes to scope a spot and zip tie the thing on. The Flashbak is going to take a bit more thought, but I most likely see myself using it just like in the sample picture. I can't really see myself strapping it onto my back, but time will tell. If you have experience with the product and want to submit your own reviews, free free to give us a shout out. And if anyone was inspired by the review of the Bike Brightz product and bought one, we'd love to hear from you too.
