Took the plunge and order this bike light set with no review on Amazon. I figured worst case, i can return it. I did not have high expectation for a cheap light set. The light is for the kid riding around the block in the evening and with daylight saving, it start getting dark at 6pm.Received the lights yesterday. The light set is well build, solid. Doesn't feel flimsy for sure. Easy to use. Just one button on/off.What i liked about the light- there are 2 lights in the set . The front have on/off. The rear have 4 or 5 mode. RED ON, RED fast flash , RED slow Flash, RED and WHITE flash, and WHITE. The WHITE is the bonus to me. I am using the rear light as the headlight for another bike!- I actually don't believe 210 lumens as claimed when i bought the item. Its unheard of to find 200 lumens light for that cheap, and that for a 2 not 1. But wow, the light is super bright. I don;t have any light meter, but this light is very bright. I actually have to remind the kiddo not to stare into the light.- took a ride just to test out the light. Its bright, good spread and car can definitely see you from afar. I have the light at 0 degree, so i didn't really test if it can provide enough light to see if front of you. Since i'm on paved road with street lights, my main goad is for others to see me coming.- The light works right out the box, I did not have to charge it before use.What i don't like- Nothing really here. If i have nick pick, maybe the rubber band may not last very long. Its pure speculation on my part. However, it comes with 4 rubber bands total for both lights. At least you have spare. I like this light so much that i went ahead and but another set for my wife's bike.
