Although the armband does a good job of holding my phone in place, the plastic window protecting the display does not allow me to press the Home button on my iPhone 7 plus.

I'm a small-framed female, and it does look really big on my upper arm, but it works well and so far it stays up fine

Perfect fit for my iPhone 6 plus with a calypsocrystal leather case, stays put while running and does not hold sweat while working out.

The new home button on the iPhone does not work from under the plastic protective screen.

Third, this things sure does soak up the sweat, but don't worry it dries out before the next days run, and if you so chose some mild soap will get rid of the sweat stains if you're worried about germs and such

The material of this band is flexible but does not breathe well so anticipate a sweaty arm in the area of this band (more so than that expected of general exercise).The band length is an issue for me

The only thing I do not like is that the clear screen does not allow me to work my phone.
