I had the Pure on my iPad Air as soon as Bodyguardz released it...until today. Bodyguardz makes a great product, but it's overpriced and the replacement policy is also overpriced.
I just put a Zagg InvisibleShield Glass on my iPad Air and it's freakin' awesome. I had a Pure on my iPhone 5S until Zagg came out with that as well...replaced that too and won't look back. The oleophobic coating on the Zagg is EXTREMELY smooth and the edges and around the home button are rounded rather than sqauare. It makes it feel like there's nothing on the iPad.
The BG Pure retails for $79.99, which is REDICULOUS. You can wait for deals, but I still paid $39.99 on Black Friday. The Zagg Glass retails for $49.99, but I purchased over Memorial Day weekend for $24.99. Zagg & BG have deals from time to time, but not that often.
Now the replacement policy. BG will replace your Pure for $29.99, no questions asked. You simply have to return the "bad" Pure to them (at your cost) in order to keep the warranty maintained. Zagg, however replaces the Glass for FREE for LIFE, no questions asked. You have to return the Glass (at your cost) in order to keep the warranty maintained.
Personally, retail price aside, the Zagg Glass blows BG out of the water simply with the warranty. However, with the cheaper retail price as well...I think it's a no-brainer.
I liked the Pure...I LOVE the Zagg Glass. I steer anyone I can toward Zagg...I've used their products since my iPhone 1...and their warranty has ALWAYS been second to none. The only reason I went BG was because Zagg didn't offer a glass protector at the time. Now I'm back with Zagg.
(Just so everyone knows...I don't work for Zagg. Just love their products. They've treated me EXTREMELY well over the years and their products are awesome. To be fair, BG has also treated me EXTREMELY well.)
Just my $.02.
