For like the first two months I had it in a gel case so maybe like two weeks without a case.
No major scratches, think all scratches are near the the charger port since I tend to plug my charger at night in pitch blackness sometimes and miss the port.
Currently rocking a Centra Case that has that sandstone feeling like the original One Plus One phone had. https://www.amazon.com/Centra-Lightweight-Durable-Retail-Packaging/dp/B01A182XJQ/ref=sr_1_1?ie=UTF8&qid=1486769313&sr=8-1&keywords=nexus+5x+centra+case
