Constant clicking sound due to fit not being snug

I initially loved this armband however there is one very GIANT flaw: the way it connects is not via a magnet, but rather 2 small little clips that hold the metal square which have indentations on the sides. The problem is, if running or moving your arms in any way, the fit is not snug and the weight of the phone (I have an iphone 7) pulls the metal up and away from the backplate and it makes a clicking noise...with every single arm movement. It is driving me crazy! If that small circle in the center is actually a magnet, it is not nearly strong enough to do anything with real movement. If it had a powerful magnet that would actually keep the 2 metal pieces from separating, it would be great. Very bummed. I bought a new case just to be able to use this (my old case was textured and thus it wouldn't adhere). One other thing that bothers me is constantly having the metal square on the back on the phone. It's slippery when you put the phone down face up and any gripping quality of your case is irrelevant, unless you put your phone facedown and can't see the screen. And, pressing the home button while flat on a table and the phone tips/rocks, which is also just an annoyance to be aware of.
