I had read the review stating that had to cut two small plastic tabs that protrude into the housing of the SuperDrive, as they prevent the good clip. It helped me very quickly and this allows to have a functional external together.
Regarding the trolley itself, I realized too late that the model corresponded to a mac book pro but not of the series that I bought. The connector was different (ATAPI instead of SATA). Very disappointed, I wrote to the support and what a surprise to receive a return within 2 minutes. After some discussion to check my setup and my serial number, the carrier proposes to send me another caddy format. A few days of waiting later, here it is installed, I am very satisfied, especially the customer service that I find exceptional.
Conclusion: be careful with its serial number, do not hesitate to contact the support BEFORE make the purchase because there are several different sizes of connectors.
In use, it's great ...
