Top critical review
Maybe I won't say "beware" but I will say "BE AWARE."

I'm going to get to the problem with these right up front. The issue is that this adapter bracket is missing the bottom 4 mounting holes that all 3.5" HDD have. it has holes to properly mount a 2.5" drive to the bracket, but the bracket in turn MUST be mounted via the side mounting holes. Mounting options for all 3.5" drives includes side mounts and bottom mounts. All of these holes should be tapped for standard computer screw threading, which is sized #6-32. The case I needed to mount these in uses quick release trays for which I needed to use the 3.5" bottom mount holes. Mount holes not present on these adapter brackets! Because I wanted to complete my project and also not deal with returning $6.50 worth of stuff, I went ahead and carefully measured, drilled, and tapped the 4 proper #6-32 holes in the bottom of these. Then they worked just fine for me! That was a hassle I didn't need, and honestly I'm pretty sure most folks that would get these wouldn't be set up to do that even if they were willing to for some strange reason.
Anyway, I would have given these adapter brackets 5 stars if it weren't for omission of those bottom holes, but really, that is a pretty glaring omission so 2 stars it is. If you can get by fine using the side mount holes, then these are nice powder coated sturdy gauge steel brackets. For myself, I would not buy more of these even if I did plan to just use the side holes. The reason is for future flexibility. If they should ever end up in my spare parts , I want to have confidence they will work in any and all standard ways.
