Just taken with Samsung SSD 850Pro in operation. Installation without tools and easily. Then just make a clone with Carbon Copy from my MacBook Pro HDD to the SSD as a new internal HDD installed. Housing done so far his service as it should. Only the plastic of the case seems to cheap and relatively easy to break. Am sure how many times you can not open the case and close it again until the first pin is broken. Therefore, only 4 out of 5 stars. A silver version for Mac would also be desirable.
