The device seems pretty well made and it sort of glows bright red and then less and then more, etc. It does not have the strobe blink like other rear "blinkies". The mounting flaw is disappointing in this USB rechargeable unit. Light and Motion suggested that I purchase their 70 lumen $100 VIS 180 which can be positioned to point directly rearward. Sure, fine, seems really bright but $100??? Discuss....
There must be something missing from the mounting bracket on yours, the VIS 180 micro has the adjustable mount like the more expensive VIS 180. Take a look at the side-by-side here

That being said, I wish I had purchased the larger unit, the pulse on the Micro is anemic.
