Query: Ruined the functionality of my Fitbit blaze.

The concept is wonderful. I love how stylish it is. However, it doesn’t work well. It basically ruined the buttons on my blaze to the point where I had to call Fitbit support to walk through a hard reset for my blaze. They blaze works well in other bands but this one is way too tight. It may be a defect of the one I received.
