VUP Detachable Running Phone Holder 360°Rotatable Armband for iPod MP3 Player iPhone, Fits All 4-6.7 Inch Smartphone Device, with Key Holder for Running Hiking Biking (Black-Detachable)

Works as advertised. The added benefit is that you can use it to turn your phone into a bike computer. The strap will fit nicely over the closer end of aero bars.

Seems sturdy. Fits my iPhone 14 plus with a large rugged case. Twists on and off easy. WARNING: if you have large upper arms. Muscular or otherwise this might be too small for you. I don’t consider myself to have large arms. Perhaps middle of the road and I only have a little bit more room to make it bigger. I can see this getting sweaty and stinky really quick. I’m not sure how easy it will be to clean. I wouldn’t recommend using this while doing any kind of bicep curls, or anything where your arms are going to be flexing and pushing on the elastic. I don’t think it’s the best quality and I can see it getting worn down fast. The spikey part of the Velcro is small so I can see that wearing out fast and possibly coming loose if enough pressure applied to making the band expand during weight lifting.

Why did you pick this product vs others?:Not bulky while using the swivelFunctionality:Easy to rotateVelcro hold:Great grip on tightness

At first, I was a little concerned that the rubber webbing wouldn't stretch enough over my phone. While it is a little tough to stretch, it's actually a little more secure because of it. Once the webbing is around your phone it's not going anywhere.This armband is similar to many I've had in the past. Your typical loop and velcro. The difference with this one is that there is a place to store your key when you go running, a place for the wires for any non-Bluetooth earbuds, and no plastic-type pocket. It's a simple yet very functional design.If you're used to the classic "pocket" armband for your phone when running, wearing this armband with the phone attached takes some getting used to. At first, it feels like the phone might fall off because it's not sitting in a pocket but it truly doesn't move. Once you get past the nervousness you realize that you can now run and exercise without having to worry about your phone "sweating" inside a plastic pocket. Like you, the phone can breathe easier. The simple method of 'push and turn' to lock your phone in place makes it a quick add-on for any run or exercise. It's also easier to navigate through song choices without having to take your phone out of the pocket or trying to move your arm in odd ways to see your phone.I had been having trouble with my classic "pocket" armband and after my runs the cameras on my phone would look foggy. A couple of times I needed to use the old rice in a bag trick to get them back to working condition. With this armband I don't have to worry about keeping rice on-hand waiting for me when I finish a run. The design allows for airflow around the phone so there's no condensation build-up. I was pleasantly surprised and I'm very pleased with how this armband feels and functions.

Why did you pick this product vs others?:Do not buy. Product requires you that you have a device that measures blood sugar. The device does not measure blood sugar independently. It only records data.

Kind of flimsy for an iPhone 13 Pro. The straps that hold it in don't seem to stabilize it too well.

I haven't wear it outside yet, but I spent some time, about 45 mins. with it attached to my 14.5" arm, and it's very confortable, akso, I checked all the possibilities to lock, unlock, move around the phone, and it works fantastic, very easy to handle, the magnetic on the holder is a great idea, it help a lot. Great product. I'll see in the long run how it fairs. Finally, had a run yesterday, 42 min., and it feels like nothing on my arm, this is very confortable to wear indeed.

I was looking for an armband that wouldn't be in a pouch that causes condensation inside and I liked the idea of having access to my phone at anytime. This armband did provide those two things, however it caused me other problems.1. My phone shakes horribly while I run. I am a fairly smooth runner and run 8 miles each time. I have an iPhone 15 Pro Max, so it is a bigger phone, but the shaking of it drove me crazy!2. With all this shaking, the armband gave me a burn on the back of my arm and actually cut into my arm. I had to take it off and carry it the last few miles of my run.3. I already have it as tight as it can go, so tightening it won't help. The phone sets too far away from my arm and that gives it too much wiggle room.I will say, the phone did stay attached to the band, so it is a snug fit.Very disappointed to have wasted money on another arm band!
