Interesting stuff, but it wearing off in a week makes it a no-go for me.
I prefer the Lightweights stickers. They come in a variety of shapes to put everywhere. I used some to put on all the spokes of my bike, others on the gloves I wear in cold weather (stickers have easily survived hand-washing) and to add more reflection to my high-vis (but not reflective) bike vest, on the paniers of my cargorack… I also used their Stealth Tape all over my bike’s frame. I look like a regular Tron character when you shine light on me.
Of course, all that’s on top of regular bike lights. I’m partial to Cygolite’s, currently using Dash 350 with combo red rear light. Thinking of upgrading.
Didn’t stop that guy from blowing through their stop sign and almost running me over the other week, but I like to think that it has at least reduced the likelihood of that happening. It was only the 3rd scare I got in 2 years of bike commuting, but then I’m lucky with an 8-mile commute that’s nearly all residential and/or has bike lanes.
