Dust and dirt get underneath and will show...the two clear cases I have are both scratched pretty bad after two months of use. You don't notice the scratches unless you take the cover off and look through it which I do every once in a while to clean the dust that gets underneath. The clear covers are still what they were new. (clear) They work for me because it adds grip to my 6 Plus, looks like I don't have an obvious case, protects from wear, and keeps the camera lens off the surface when you lay the phone down. I use the i-Blason from Amazon that costs less than $20. Maybe some are more durable but for the price paid its a good investment.
