I was looking to get the Belkin SP since I have an Apple store close to me. I figured that Apple would provide a great screen protector to go with their high end phone. The fact that they do the install with a Belkin installation machine pretty much had me sold. But then I saw that the reviews were awful, with lots of screens cracking without the phone being dropped.
I ended up ordering something else after reading that Apple was telling folks they were stuck, since I they didn't warrantee accessories. I was shocked, but several reviewers said the same thing. $40 for a SP with crappy reviews, and Apple won't stand behind the product? No Thanks!!!
I ended up ordering an iCerez off of Amazon. Amazon has a better warrantee/return policy. Their products are cheaper, and often times have much better reviews. I won't buy accessories from Apple when Amazon and others provide better prices and warrentee/return policies. Best Buy also has better warrantee and return policy.
If you want to try the Belkin Roulette, go for it...
