Check out the comments if you ever order from a dealer.
As for me, I strongly AGAINST 12w 1Foteam alias. Indeed, I noticed a price drop after Amazon has fulfilled its stocks and have therefore contacted the dealer and request a refund of the difference, which was denied. That I can accept but I honestly saw red when responding to their service on the price: 6 hard drive costs "taking into account shipping costs, upstream logistics and operation with our trading partners. " I am willing to be nice guys but ... Do not mess!
Otherwise, regarding the hard drive itself, I did nothing wrong because my home, they work perfectly!
I will not hesitate to change my review if something changed!
