Arrived on time.
Comes with 12 screws: 4 for attaching the adapter to the PC case, and 8 for TWO hard drives to attach to the adapter.
Very simple and easy to install into computer case.
Sits tightly - no movement of hard drive.
Plastic is weak/flimsy.
On the corner, where one of the screws would go in to attach the top hard drive, this was broken off upon arrival. Top hard drive is still attachable with 3 screws. Didn't bother sending it back at it only cost about £2.
No screw threads in the holes. It's easy to screw in the screws, but BE CAREFUL to not over tighten them, as this very easily destroys the thread in the weak plastic.
Packaging was not very good. Came in one of those plastic zip bags, which was then just inside a grey plastic postal bag. No padding or anything, hence the broken corner.
Despite all the bad points, I still recommend it to others if they are looking for a CHEAP adapter/bracket that allows 2.5" HDDs or SSDs to fit into a 3.5" slot. Just be careful not to destroy the screw threads you make in the plastic, and don't throw it around!
