Simket LED Armband Rechargeable for Running(2 Pack), Running Lights for Runners, Running Lights, High Visibility Reflective Running Gear Adjustable Light Up Arm Bands for Men Women Kids

Bright, really cool, mostly work for my intended purpose (costume related) with minimal alterations.Worried that the rechargeables won't hold up worth a damn though. Had a lot of problems with small rechargeable batteries in products like this lately.

Very very bright excellent product for night running

Works great, recharges easily

These light up bands make a huge impact for nighttime visibility. I feel much safer when wearing them. This was a great purchase, until I discovered that one of the two bands doesn’t recharge which is very disappointing.

I bought the wristbands in November 2024. I’ve been very happy with them. They recharged nicely and they last for a good length of time in between. Nice and bright. I’ve got a lot of comments from the neighbors.

I think this is a great product for those of us that use the coolness of the night to ride (or walk or run). The light output is great to identify me to drivers when close (I use a taillight to be seen from a distance.) so I can flag my turns with hand motions. I liked it enough to buy a second set in red for my right side.However, the green fabric encloses a piece of spring steel which provides the grip to my wrist and ankle. But that fabric has begun to separate exposing the steel--potential for rust and digs into my skin. And I cannot find a way to talk to the manufacturer.POST2: Tried to seal fabric with glue gun, but that did not last. I appreciate that these will not fall off while running, but they irritate. Basically, the spring steel is too thick; could be half or less the thickness.Now the switch on one of the four units has gone bad and is non-functional. And the battery on another is starting to die requiring charging after a couple of hours of riding. I may have 100-150 hrs of use. I would have expected more. (NOTE: Supplier made no claims as to MTBF.)Because of these two additional issues, I am downgrading my original score to 1. Again, I like the concept, it just seems to have been poorly executed.Aug 2024 UPDATEAS noted above, I bgt 2 pair in Jan 2023. The last band has officially died. (48 hr charging got about 5 min of light.)Battery life range is appx 100 to 200 hrs.Also, I could not think of a way to wash the cloth cover--given that the LED lights are enclosed. After about 100 hrs on my wrist/ankle the sweat (I live in humid Houston) started to build up and stink.Will not be buying them again. Hoping to find a better alternative.

Really happy with these. They are like "snap bracelets" and can wrap relatively comfortably around wrists, forearms, upper arms, or ankles (depending on how thick my clothes are) so you should be able to find a place to wear them easily. They hold power for awhile (I'm yet to even need to recharge them so far, though I'm not a daily user). They are easy to put on and remove, stay stable in place, lightweight, and the color is bright and crisp. I feel very visible wearing these at night.

Very happy with these! I’ve put them through about 9 months of very heavy use, and they are holding up well. The battery life is way better than I would have guessed. I turn them on for some amount of time every day (depending on how early it gets dark), and I go about 2-3 weeks before they need to recharge. They charge up fairly quickly too. When lit up they are super bright. They are nice and reflective too, so helpful even when they are not turned on. I use them for biking, and store them on my bike. So the color has faded some from the sun. Doesn’t matter when they are light up, of course, but it does make them less reflective than when they were new. The little flap to cover the plug is useless, and doesn’t stay in at all. One fell off, so I took the other one off too. But, I have ridden in the rain with these numerous times by now and never had a problem. The metal band inside has poked out of both bracelets, but I have fixed that with gaffer tape and it does the trick. Biking is my main form of transportation, so these get a ton of wear and tear. Very happy with how well they’ve held up, going to buy another pair for my spouse!
