I purchased their 256GB+64GB Micro SD memory cards set for $39.99 (includeed a free 64GB card). The card appeared to be genuine when you check the properties. But in about 6 weeks 256GB card died in my smartphone and detail analysis (H2TestW is a free download soft) of the rest 64GB card showed just 8Gb real capacity. When I wrote them and they replaced me both card the story repeated 2 times. Now I have a lot of mail from Usadiscountwarehouse and one fake micro SD card.
Totally I checked 7 fake Usadiscountwarehouse cards (all were about 8GB capacity). I think this is realy criminal business.
