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 ⭐️⭐️⭐️⭐️⭐️

Use these around my bicep for early morning runs and they stay in place and are extremely bright. They even lighten the road under my feet some. Holds charge great and recharge quickly. And you get two of them. Great buy for morning and nighttime runners. (And they fit around my small dogs collar too for night walks!)

I bought the orange colored arm bands and when fully charged, they are very bright at night. I don’t have big arms and at times I felt these bands were a little too tight. But when I lowered them on my arms, they have a tendency to fall off without my noticing it. So I wear them above my bicep, over my puff winter coat, and they don’t ever fall off. Plus they will be tight enough in that position so you can definitely feel them and not have to keep looking to see if they have fallen off. The downside is that after a few uses the bands no longer flatten out and stay in a curled up position after you take them off. This makes it a bit difficult to get them back on, but it’s doable. As for the charge, I wear them for about an hour every night on my dog walks, and they start to get dimmer after the third or fourth day, and you will have to charge them again. They charge up quickly though.

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.

Used these light up bands for skiing! I can spot my kiddo coming down the slopes very easily now!!! She got so many compliments and so many parents want them now. Very bright, easy to charge, and super comfy! We bought the pink ones.

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.

These are perfect for star parties and using the blinking reds around the legs of the tripod is wonderful. Make sure you charge 'em up before you head out. (Too bad they used miniUSB instead of USB-C for the charge port)You have to buy two sets to get the three legs covered, but the extra one is good to put around your arm or around other parts of the telescope. Makes moving people around your instrument much easier and safer.

Worked okay for a few weeks, now one of them will not hold a charge. I put them both on charge after I'm done using them, charge them all the way up then unplug and test them. By the next morning when I try to use them one will not turn on at all.The other one still works fine, though.
