The perfect solution for how I wanted my phone mounted to my bicycle. I really like how easy it is to find and use an attachment for anything. I have a mount on my mountain bike, car, road bike, and an armband. Even after a rough spill on the mountain bike, the phone will still not fall off of its mount. Highly, highly recomened!
The armband stays in place on our long runs. The phone feels secure. The awesomest part is the quick release attachment. Snaps on and off for easy mid-run app/music fussing. I used to fumble with the armband sleeves or carry my phone. No more! Paired with wireless headphones... we could never go back.
I was worried that this wouldn't work well but it does. It's great that you can take it off and put it on another vehicle. It's easy to use with the quick release. As a plus once you put the ring on the back of your case you can use it with all the their quick mount products.
Best running armband EVER! Yes, having to put a quickmount onto your case is very inconvenient but the connection between the two is so convenient, durable, and trustworty. I can take my phone off my arm to snap a quick picture of the scenery during a run or send a quick text without having to stop, etc.. I've had this case for more than a year and I've had no regrets with this. There is no way i will ever go back to a pocket armband.
