Functionally, it works quite acceptable for its money, if you know how to work with your hands, then you can safely take it, because you set this miracle once and forgot it. I don’t know if it’s worth listing this as a disadvantage, but, although it already sits quite tightly in its place, it didn’t work to fix the Optibey with a screw. There are a couple of holes for this, but they do not match the regular ones on the laptop case (sony vaio VPCSB1Z9R). We will test such use without fastening, and, perhaps, we will have to something . Well, the situation with the plug is also not encouraging. If the seller sees this comment and sends it, I will indicate it here.
