Product is very good.

For product:
Have 6 pieces (3 pairs) at a price of 7.83 euros per couple and ordered all the test program H2testw.exe of c't tested. All products are working properly, the capacity is in each case 7.8 GB = 7.26 GiB. Each of the Class 4 cards (4 MB / s) managed on my 5 year old netbook (no antivirus software) 8.8 MB / s, the test program but which generates very large files (each 1 GiB) - the result is the Class -4-measurement may not be comparable to, but the value is excellent safe for Class 4.
Also positive: Each card came with its own plastic bag. These casings without card sold some traders for up to 2.50 Euro / piece!

Two points to the dealer:
Bad is the additional cost of 3.49 Euro of agency 'Memory Man' for payment with the Amazon credit card, the shipment was for free. I have a real account and do not get (bad for the tax return and for any complaints), in an upholstered letter were only the cards. For the weaknesses of the trader, there is a star deduction.
