It's a bit hard to get on and up high enough on your arm to fasten one handed, and you have to make sure your have your playlist queued and such before you put your phone in the case because the LG G4 doesn't play nice with its sensors being covered, but it's overall a pretty good deal for the money.

but I can't fit the band around the top of my arm, only on my forearm which stinks a bit

Started to crack a bit but that was after a lot of heavy use

I wanted a good arm band for working out for my phone, and while it does the job, its a bit tricky in design in getting it on and is a little too big for those of us with thin arms.
