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

We use these on our bikes and ourselves (arms, legs, back of backpack, bars of the bike) when we have to travel at night. We have an e-bike and I don’t think I’d ride it in the dark at all without these.They are incredibly visible at night, (the green ones even draw some attention during the day), and are super versatile with where you can use them. I specifically sought out the slap-bracelet style to use as a pants-cuff but was also delighted at how easy it is to attach these almost anywhere.Love that they’re rechargeable, and the split charging cable means you can charge both pairs off of one USB outlet. Awesome design. (One side of the cables we got doesn’t work, but I didn’t bother to send it back because we got two pairs and it’s been easy enough to charge three at once and swap out the fourth.)A single charge will last you a good while, zero complaints about longevity. (Don’t leave them sitting on the charger past full recharge though, most tech items don’t do well with that.)100% recommend and would definitely buy again. Incredibly effective for visibility and safety ⭐️⭐️⭐️⭐️⭐️

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 am very happy with these! I’m training for a marathon and it’s so hot right now that I have to start in the evening. These make me feel safe and seen after the sun goes down!

Fits on wrist or arm. I use it so when walking home in winter I’m less likely to get hit by cars when walking home from work. Came without instructions, but is fairly intuitive to use. Except for knowing when light is fully charged. There is a tiny tiny light by the charging port that turns green when it’s fully charged. I asked a question on Amazon and the answers said when the light turns green. Well they never said where that light was and it was only by chance that I saw the light. It works great, I give it 4 stars not 5 because no instructions were included, otherwise a great product.

I use these more as a wristband due to the size of my biceps, they fit tighter and better on my wrists and don't feel like I need to constantly re-adjust. They are great for night time walking and knowing that I'm truly visible.The charging topic makes these highly re-useable and great, the only thing you need to do is use the dual charger and a USB-A charging brick. The indicator works great to know when they are charged and glad I bought these for use!

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.

Our family participates in a run club with 3 kids. These are so fabulous to keep track of them and stay visible running after dark! Slap them on the stroller, arms, ankles, water bottles. Charger works perfectly and they’ve never died on us- all the parents comment how great they are, many of us have reordered.
