This is a COROS Heart Rate Monitor that I've used only a few times. There's one dirt smudge on the band that I could probably just wash off real quick, but I am always nervous getting water near electronics. Anyways, it works great - I just...never use it. I really thought I was gonna be a HR monitoring girl. But turns out my heart rate is just always SKY HIGH, which I can tell by the way it feels as though my heart is going to jump out of my chest at any moment, so all an electronic thing does is increase my anxiety about it. Wheeee! Anyways, super great heart rate monitor, works perfectly, looks cool on your arm or whatever, pairs with your phone, and comes with the box, charging cable (which I forgot to photograph), and instruction manual. *** Please note that I live with a cat and even though I lint roll, a stray hair or two may end up in the package - please be aware if you're highly allergic! **
