Works greatLo coloqué en en una mochila, y podría decir que incluso a mi me da miedo mirarla en las noches oscuras jeje. Muy útil para mi. Desvía las miradas de los curiosos y a las vez les atrae la curiosidad.goodeasily attached, glow in the dark. very cool looking day and nightJust received them today and the Velcro just started unstitching. Not sure if i just got a bad one or they have an issue with quality controlSafety factor so I won't get hit by a car, from the rear. And my CAT can find me in the dark as well!I bought two different versions of the four.Give 'em a look . . . THEY look BACk at-cha!Nice, easy to install on the webbing on the back of my backpack. Installed for fun, not safety (for that you should get something retro-reflective). If they start falling apart unreasonably soon I'll update this. Not giving all 5-stars as I don't know yet.I'm not going to say exactly what my job is but on occasions I have to wear a ball cap and walk around the dark. And when me and my fellow compatriots have to walk around in the dark together this item makes our job so much more fun because no one wants to walk up on something that has eyeballs like this. It is definitely creepy and it helps keep the boogeyman away. ?‍♂️?‍♂️?‍♂️
