I found this on my junk mail, the deal is the same as previously posted here but it's expired. The review I read from this website stating that the benchmark is pretty good for class 10. Apparently this micro-sd also shock proof, water proof and magnet proof(care to try?).

Cheapest I found on ebay is $35 shipped for buy it now.
I probably won't buy it because I prefer sandisk 64GB micro sd that apparently worked with Galaxy note
Why the hell would an SD card need to be waterproof or shockproof? Pretty moot considering most phones aren't waterproof and their screens will crack when dropped from more than 2 meters.
