The Quality Of This Product Was Very Excellent. I Bought This Product Because I Was Running Out Of Space On My Hard Drive. I Also Noticed That When You Delete Files From The Flash Drive The Red Light Blinks To Show It’s Working. I Installed What Came With It, The Device Works Perfectly, I’ve Noticed That It Has A Vault, The Vault Is Optional Because I Don’t Use The Vault At All, After I Installed What It Took To Run The Flash Drive I Just Went To My Computer And Copied Movies Normally, It Worked Fine, The Movies Run Just Fine. So Far I’ve Been Able To Fit 6-7 Movies On One Flash Drive. I Haven’t Put Any Audio On It Yet. Thank You.
