This adapter is accurately made, robust, well-finished, and supplied with suitable screws. If you want to mount a 2.5" drive in a conventional drive bay and connect cables directly to the drive it will probably be very good - 5 stars. But if (like me) you want to mount the drive in a caddy belonging to a chassis with front-access drive bays it's useless, because the adapter DOESN'T give the drive the form factor of a standard 3.5" drive: the electrical connections on the drive+adapter combination are in a completely different place, so it won't fit a drive bay with a fixed socket. 0 stars this time! It would be perfectly possible to make an adapter to give a 2.5" drive a standard 3.5" form factor, and then it would work in any kind of chassis; I can't imagine why Quantek don't.
