...Okay, I have a long rectangular white box sitting next to me which should contain the " Apple Watch™ 42mm Stainless Steel Case - Milanese Loop" that I ordered two days ago. I have been reading the reviews here and still cannot decide whether I actually need a screen protector - and this screen protector in particular. My experience with Zagg has been mixed. On my first iOS device - an iPad Air 2 - it shattered when I tried to lift the bottom left hand corner and I just threw it away. Zagg worked fine on my iPhone 6 Plus and I just received the Zagg protector for my iPad Pro, which currently has a Tech Armor protector, and will be replaced tomorrow.

So I trust the brand, and they do have excellent customer service, but they can be a bit dodgy at times - if you click a visual link to the product on Zagg's site, for instance, you get to the dreaded 404 page.

I want to take this thing out of the box and just go at it. Is the Sapphire Crystal "good enough" or not?

I know that I'll get into the box sooner or later – very much like the kid at Christmas who knows that there is no way that a box that small could contain the Encyclopedia Britannica but dying to see what's in there, nonetheless.

Just need three answers - one from someone who high-fived it and couldn't live without the peace of mind that if affords, from someone who hates it with a good valid argument of why it's unnecessary and finally a two-three star reviewer who can make arguments for or against.

Thanks.
