QUALITY AND SPEED :)

Excellent card, fast and constant flow, especially tested without any errors with H2testw 1.4.
At a time when lots of vendors on other sites sell tampered cards to 64GB for just less than one, at least with Amazon it is covered in case of problems, and the quality is at the appointment.

Results of the test write + verification of written data:

Warning: Only 59935 of 59936 MByte tested.
Test finished without errors.
You can now delete the test files * .h2w gold verify em again.
Writing speed: 15.4 MByte / s
Reading speed: 17.9 MByte / s
H2testw v1.4

Admittedly, this is unless advertised by the seller, but notice little difference in speed between reading and writing pass, and personally I prefer this, a homogeneous flow between reading and writing, it is rare for highlight :)
