The device was supposed to be missing in any PC user to help themselves. The adapter has worked very well at first. I've used it with several SATA and IDE hard drives or DVD drives, test for example to back up and migrate data, for installation or simply whether an old drive still works or not. The device can of course raise no defective drive to live, but it is good good for easy diagnosis. I used the drives built in time-consuming external housing. Today goes quickly with easy plug in the connectors. A protective sheath, such as Fantec 8.9 cm (3.5 inch) HDD Cover for HD can be useful. But should be used external housing for a continuous operation of Speicheern and drives. Actually, everything is explained by the device itself. The indicators show the function. The connectors fit reliably. Something Kabelwirrwar is to be accepted. The connected devices must be secured in the context before falling off the table. Experience value: I just put this all in an open cardboard box. The unit was to me among others very helpful in reinstalling modern micro-PC (Intel Atom D525 (Dual Core) ION2, 4GB DDRIII, 500GB HDD, BluRay, silent (Slim style)) in order for the substitution was necessary from the Old PC to take over. Price and achievement are correct. Buy Empfehlenswert-!
