Firstly the bag can really hold a lot of things so if that's all you're worried about then it should be fine . Features that didn't work for me: Basically, I need an armband so I can easily wear it during my workouts. Well my arm is too big for it so the elastic is probably too short and if I try to stretch it it will hurt me and will most likely cut my blood circulation! So I tried to give it to my little sister whose hand seems to be too small because she keeps slipping while walking. The rubber band doesn't work very well. Or maybe it only fits certain hand sizes. Your phone also doesn't have a front support as you can see in the picture, it's just flimsy plastic. So if you drop it face down while exercising, your phone's screen will shatter. If you buy one, make sure you have a screen protector, or use a different phone case, then put everything in that one. Not sure how waterproof it is as I didn't want to risk getting it wet. . From the looks of it, it doesn't offer any more water protection than putting it in your pocket. It's also very awkward to wear, whether on your arm or just holding it. I don't recommend it.
