Received but haven’t tried them out yet

I purchased these for my kids' bikes. Super easy and universal to install. My son took a small fall and cracked it. I'd purchase again.

Great design and elasticity on the rubber to fit around just about any bar size. The lights are not too bright, but they are also bright enough to be helpful. Easy to press on/ off/ mode change button at the top. Recommend for all ages.

Update:After I left my initial review (see below), the seller kindly contacted me to ask how they could make it right (whether that be by refund or replacement). Upon weighing the overall positive reviews for these and figuring perhaps I had received a “bad batch,” I opted for replacements. They were received extremely quickly and I am pleased to say that, after giving them a thorough test over the course of 2-3 weeks, these lights are worlds better than the original batch I received. They are EXTREMELY bright and the strobe mode really does help me get noticed by NYC cabs, buses, etc. while I’m on my scooter. In fact, the one (out of four) of my original batch that actually worked has been attached to the back of my helmet since I first got it and it is still going strong. I have updated my review from 1 to 5 stars, because these do exactly what they are supposed to do at a good price and the truly admirable customer support won’t leave you in a lurch if for some reason they are not as expected.Original Review:I just started riding an electric scooter from my new office to the train station (to avoid having to take 2 subways) and quickly decided I needed to make myself more visible on the NYC streets at night.I put a couple of these on my handlebars, one on the steering column and hung the last one from my backpack. When I got out to the street, I turned them on and they were very bright and flashing away nicely. By the time I got to Grand Central (about 8 min.), one of the red ones had shut itself off...and hasn’t worked since. The opposite was true of the other red one. No matter how many time I clicked it or held the button down, it would neither turn of nor even change modes. I decided to throw it in my backpack and deal with it on the train, but after 5 or so minutes of the same, I finally had to pull the batteries out to make it stop. When I got home, I re-inserted the batteries and, like my other red one, it hasn’t worked since.So I basically paid about $1 per minute of total usage for these. Needless to say they’re going back.

Chose the 4 white lights option and still received the 2 red and 2 white. Otherwise decent product

This could have been a 5-star review because I think these little lights are great. Lightweight, versatile, and fairly bright for the price. I use them on my handicapped dog's cart for night-time walking. Both the red and white lights are very visible from a distance of at least 2 blocks (maybe more but that's as far as I've gotten from them). The white lights are bright enough to mildly illuminate the path directly in front of my dog so he can see a bit more clearly the ground in front of him. These are NOT as bright as flashlights though (nor did I expect them to be).Minus 2 stars because one of the red lights was defective. The button didn't work properly. It would take many presses to turn the light on, then many more presses to turn it off, until finally the button stopped functioning completely and the light wouldn't turn off at all. Still would have left 5 stars had the seller replaced the 1 red light as he promised in an email.I wouldn't go as far as to discourage anyone from buying this product since the functional lights do seem to be a good product so far (have used the white lights for about 3 weeks now). But I would say definitely start using all of them right away for a few days at least so you can catch any defect before the return window runs out. Reading some of the other reviews, it seems like the red lights have more of a tendency to be faulty. Maybe a bad batch.UPDATE: Increased rating because the seller contacted me after reading my review and resolved the issue. Having had these lights for about 2 months now, I am still deducting the 1 star because the batteries that came with the light seem to be inconsistent.I used the 2 white lights together. After a couple of weeks, 1 light went dim while the other is still going strong.I also used one of the red lights very periodically. That died surprisingly quickly. I used the blinking setting on that one--maybe that's why?Anyway, I expected the original batteries to last longer than they did. But since seller refunded my payment, I can't really complain. I'll just leave with this -- when they work, the lights are awesome!
