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

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.

Light up on bands are walking in the evening

Excellent warning light for outdoor activities. I walk a lot in the morning and when traffic approaches I turn it on. Had it for a few months and haven’t changed it once. For safety reasons I recommend this product.

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.

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.

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.

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!

These armband lights aren’t the best. After a few months they lose the ability to stay flattened out when not in use which doesn’t really matter to me. I ordered some new ones after about a year and one of the new pair didn’t work and had to return and get them replaced. They make me more visible when running so that is what’s most important.
