This is a good space saver but be careful and aware that as much as you can have 2 separate drives in your box. All your eggs are still in 1 basket if it gets dropped or knocked off, wet, stolen, fire, hurricane ( you get the point? ) etc. Completely separate backups are essential. As for an easy access to 2 hard drives this works a treat.
Be aware that the cables are sticking out at the back and don't exactly feel secure, very wobbly in fact. This isn't really going to be a problem if it's sat still, on a desk away from being knocked but still, it's a design fault in my opinion. A more secure usb cable/connection should've been part and parcel.
Very easy to set up and use. As easy as you dare hope, even for first timers.
My 1st one developed a fault and became inoperable but amazon sent a replacement NEXT DAY free of charge. This was a surprising & efficient service that i was very pleased with, as i was with out access to my files for 24hrs. They give you ample time to send the crocked unit back, postage paid before they charge you for the new one, if you don't. Could've been a lot of grief, but was only a minor disruption in the end.
