Instructions for use not detailed enough so I may have been using it all wrong. Biggest drawback (which should have been obvious) was in order to get 2nd drive you would need to bend and reverse the cables on a chained power cable. Also, to fit the mount holes to the case the 'handle' needed to be inside and also prevented easy access for cables, so I cut it off, fixed just one drive to it.. would have been better to buy two mounting plates. I spent an hour or so trying all sorts of combinations of mounting two disks, none were satisfactory. Sorry.
