Lots to love about this little light! Super easy to charge with USB port- no cord required (so no cord to misplace in a few weeks!). Very lightweight. Clipped easily to top of shorts, which allowed me to cover with my hand as to not blind oncoming dogs. Illuminated my path before the sun came up, and made me feel safer with respect to cars and bikes along the way. I won’t do a morning workout without this!These lights are really amazing. I walk at 5 AM at local park. To say that I’m not quite comfortable being in the dark is an understatement. I Click these lights on to my dog stroller and they really are amazing. They give me enough brightness to feel comfortable.The light is nice, bright, holds well and doesnt botter you at all while running. Had a issue with one of the lights after the returning period from amazon, the seller promptly sent a new set.Really bright, great for deliveries at night!I love itWalking the dog in the early morning hours is so much more comfortable for us. It is a very bright, lightweight clip-on and charged easily the first time. Walk on!Use it for running and attaches to my belt. Light runs for hours and is great. My favorite running light for sureSuper bright and easy to use.
