I have a few questions concerning this product..It look great. I can justify the purchase. I am wary of the external drive and have space to transfer to my HDD ( have a WD HDD 1TB external...which is now a doorstop/anchor, failed 4 days after warranty expired, Had a lot of A/C folders stored on it) Has the documentation improved since the last review? I have asked questions elsewhere and am looking for answers here. Answers appreciated from current users of this product...I have tried many other add on scenery and they don't measure up to this.. Thanks.Blades
