Review on ⚡️ Delta Cycle & Home Safety Light 2-Pack: Ultra-Bright USB Rechargeable Outdoor Lights for Night Walking, Running, Jogging, and Biking by Will Bremer

The overall rating isn't five stars but more than four I had to give due to an annoying (emphasis on ky, as in a button) design flaw: on-off buttons is (not color coded on matched the support post, green firefly on the one I chose, but) black on black: not ideal as not an option with the eye after dark: the thumb fumbles and eventually finds Braille. My remedy: what I came up with for the black-on-black arrow on the espresso machine dial: a dab of white paint that I have to reapply from time to time. Sigh. What were the two design teams thinking?
