On the face of each blade in very solid. The holes were machined perfectly, and I also appreciate the small round rubber to prevent vibration between the structure and the SSD. Personal use: My PC case has only dual-slot cage for conventional HDD, so I used this to install a Crucial M500 SSD in the floppy drive slot of the PC case (SDD does not need direct vent because does not heat). Cheap and perfectly fits my needs. Controlled PC LOOK at a price of 7.50 euros.
