Bought one to use with a new Sandisk SSD. Arrived promptly, it's fine but if your case uses brackets with studs rather than screws then you might have some issues. My case (Coolermaster) uses these and the holes required a bit of drilling before they would fit.
A good solid item, fits the SSD and HD slot exactly. It's a bit higher than stated (about 15mm) and it's a mystery why it's referred to as 2.5" to 3.5" when it's actually 2.75" to 4", but it fits the conventional HD slot.
To attach a 2.5 hard disk, in my case a SSD, into a PC bay works very well. I wanted to attach the SSD so that I could insert it into a caddy located in a PC bay but this will not work as it does not make it into the full size of a 3.5 hard drive.
Good quality metal, feels strong. Used to mount a Samsung 840 in a desktop 3.5inch bay. Both SSD mounting holes and drive bay holes lined up perfectly and no issues in securing with the supplied screws
