I have 1 OG Mini in Anodized Blue and it has been around the block about a million times and was previously owned when it was graciously passed to me by a fellow Reonaut. Considering all of that it has scratches - but they are fairly minimal and I wouldnt see that as being "easily" scratched for sure. This one has been a work horse to several folks and still looks pretty darn great.
I also have a Grand that is Black Gloss with a Red Metallic door, I managed a tiny scratch from one of my rings in the black gloss that you can *barely* see and I have dropped it and all sorts of things (no matter how careful I am - I may possibly be the *clumsiest* human in the history of ever)
And I got the SO a Raw Tumbled Alum Grand and its pretty much mar proof.
Im fairly certain that regular baths will also help prevent tarnishing and such as well. (beauty of a Reo - you can literally bathe it

)
Hope this all helps a smidge!
