The frame and the plate can be installed surprisingly easily, which is probably to write Sony diligent hard drive bay to. Nevertheless, the frame is made solid, can be installed permanently and is stable. Since nothing rattles, the plate is well kept, everything was great. The guide was short, but adequate, even as a layman installation was done quickly. The installation ran automatically and so far there is absolutely nothing wrong with the disk. Would I buy in there again, for the price anyway!
