Wanted to share my experience of Sandisk 'life time warranty' claim.
One of my 8GB Sandisk Extreme III card failed to read, write, or even format. It happen after it was use in my Canon A590 p&S (after my friend use it, I have no idea what he did to make the card unusable). I fill out the warranty claim and to be honest, the automated generate replies are really annoying. It basically sent you all the links to diagnose the problem, which I already did. I reply saying all the steps I took to verify it is not usable anymore. Someone reply with more steps and same instructions, very annoying and make you think if they even read the email you wrote.
Anyway, after some time they send me a email asking me to fill out a survey for my 'warranty claim' experience with Sandisk. I did that survey and tell them how annoying with their automated and 'human' replies for warranty claim. Couple days later someone call me and I tell him the whole experience again. The person immediately sent a return envelop to have me ship the SDHC back, couple days later I receive a new replacement 8GB Extreme III card from Sandisk.
Although the overall process is a bit tedious, I am glad Sandisk stand by its 'life time warranty' claim, which my Sandisk having problem after 2 yrs of usage (I bought 8 Extreme III cards). I am about to look into other brand but after receiving my replacement card, I will continue to buy Sandisk in the future!
Even though it can be expensive, but if it is 'life time warranty', I think it is worth it! I am looking to get one of those 45mb/sec card!
