Completely depends on what it is. One thing I can't stand is defects on screen, even just a tiny scratch or 1 dead pixel.
Liking stuff tidy, or always buying stuff new and keeping it in good condition is not "OCD".
An example of OCD: A man turns his light switch on and off 19 times before he goes to bed, because he thinks that if he doesn't he will die in his sleep.
I like to keep my things in good condition, but I'm not crazy about it
Let's say... an iPhone. When I first get it, I'll defend it with my life. However, as soon as it gets one little scratch or mark on it, I'll instantly give up keeping it safe.
My current iPhone lasted 2 weeks before I got a scratch on the screen. As soon as this happened, I stopped caring and probably had another 10 by the next week.
So yes, I am OCD until I fail.
