The installation of the plate into the adapter is very easy. The disk fits very well: no play, no wobbling. The disk tray of Lenovo but must be mounted, because the attached screws to act as a kind of retention in the context. The adapter itself fits very well into the Ultrabay bay: no gap, no play and also no wobbling.
The hard drive has been recognized after insertion into the Ultrabay bay immediately. And also the active hard drive protection - Active Protection System APS - which stops the read / write head when shaken in a split second, works perfectly.
Conclusion: Who therefore the original adapter Lenovo is too expensive, but attaches great importance to good fit and processing, is certainly served well with this adapter. Strong buy recommendation on my part.
