Screen protectors: Necessary or no?

Looking where do I find one

I still have not taken of the plastic around the watch or behind lol been using for two days.

LOL... I kept my factory plastic on until it started to peel up :) .

I found THIS thread a while back and ended up getting one from Amazon. The specific links are in that thread and offer a range of choices for both gear live and g watch.
 
Not bothering as I hate the feel of them and if I smack the watch face hard enough to break it I doubt a screen protector is doing anything to stop it. Should be fine for scratches wtc. but we will see.
 

I just applied one of these today. First impressions: It does seem to help a bit with smudges on the screen, which should improve daytime visibility. The screen protector has a good feel to it, extremely smooth. My only issue is that the screen protector is just a hair smaller than the screen. The bubbles on the edges are probably my fault, I applied it in a hurry. 20140716_195022.jpg
 
Has anyone seen a glass screen protector? I much prefer them the film ones.
