1 out of 5 eggsNot really happy

Pros: Tiny thing, looks cool, came with a usb and a sd card adapter.

Cons: Bad.
Gets burning hot when in use.
Advertised as 20 megs for writes, 70 for reads.
It's nowhere near this, it's under 8 megs per sec in real life.
Got just over halfway done checking it by hand and it failed, bad block errors in my system log and it refuses to copy more files over.
It's a bad card, weird it's a rom for 1 and you'de figure they'de check these things before shipping them out of the factory (blaming samsung here...).
I've got to rma it now, a little angry but it happens.

Other Thoughts: Samsung..., check them before letting them leave the factory, absolutely no quality control at all.
Don't give me bull about oh we check them blah blah blah, that's baloney...
