I also was not impressed with their comparison rhetoric in the "product advantages" section. It states:

"A standard bike light can be seen for approximately
50 feet, but the FlashBak can be seen from a distance
of 2000 feet or more."

What kind of standard is 50 feet for "be seen"? That really serves to undermine their credibility with such a ridiculous statement. Not to mention they went from posting that their product is visible "up to" 500 yards (1500 feet) to 2000 feet "or more" (how much more???) in separate pages on the same site. Which is it?

One more thing.....a 30 day warranty? Are you kidding? Superflash has a lifetime warranty.

Really, I am not trying to gratuitously bash this product. It could be a very good one for a particular niche. But I felt like some of these things should be pointed out. Nor am I trying to build up the Superflash (any more than it typically is). I don't even own one......I'm just using it as an example. I also understand the two products are not exactly apples to apples since they are different in their construction.....but they do serve to provide the same end result, illumination for rear safety.
