So far, so good! Nice set of 6 different colored lights. Each one works well and is clearly a different color. This is fun to attach to an item, pet or even a kiddo to help you locate them as lights go down. Definitely not for use as a flashlight but that is not its purposes or what it's advertised as. I can see it serving in a verity of applications! The clips are decently secure and we will see how they hold up over time. So far I am pleased with my package of 6 LED Collar Lights from MENNYO.
Came well packages. Each securely separated. 6 replacement batteries. All light work well so far, including their multiple lighting options. Steady, slow and fast blinking.
Great set!
