For other things should be okay, just particularly MicroSD and maybe USB Flashdrives. Personally I'm using Kingston RAMs and a few other storage cards, never had problems. Lifetime warranty for me is not really an issue, because if your item functions properly in the first few months of usage you're probably not going to have issues with it in the future. Besides, it may say lifetime warranty, but terms and conditions of claiming warranty might be limited, not sure about this but best to read up on the terms and conditions of claim. Besides, you're not really going to use it till you die right?, most probably after 3-4 years you'll be using something new and better.
It does cover the whole screen very well, and since it is wet application, it sticks to the edges. Unfortunately for my case I was not happy with the product itself, Its probably a good/okay knock off of Zagg Invisishield, you try and visit the website, all it shows is the contact email and nothing else, looks pretty dodgy to me, and the pictures used by forumers selling the product is taken from Zagg Invisishield site.
First problem was micro-dust and lint, unless you're applying it in a steam room with high humidity to make sure no dust or lint or particles in the air, the stuff will stick to the protector when you peel it off the plastic and before spraying the solution on it.
Secondly, it gives an orange feel effect, greatly reduces our Sensations awesome touchscreen feeling.
Thirdly, you will still see adhesive marks (lines) after it has dried and trust me, if you're a person that can't stand your screen not looking nice and shiny when the screen is off, you're gonna be very disturbed by the many small imperfections.
Fourth, there were some imperfections on my first SP, had it changed via warranty claim, the replacement had the same problem, applied it, was not happy, took it off and poke with fork (it does resist penetration pretty well) then threw it away. Went back to HTC specialist store and got the clear OEM SP (FYI in Kota Kinabalu that piece of plastic costs RM40-50). It has bubbles on the edges, but I can live with that, since it's barely noticeable because I'm using Case Mate Tough which covers the edges of the screen nicely.
thanks for the advise bro... really appreciate it. Been having SP issues since day 1 I use Sensation... other than that the phone rawkx!
