I used to have a flip case on my 6 so never needed one but have gone for a Mous Limitless case on my XR so definitely need a screen protector. The one that came with the Mous case was awful and had multiple bubbles even after careful application and an attempt to scrape out the bubbles with the card that came with it.
Best one that you know of? Are there any that don't negatively impact the touch response because the Mous one was awful?
