Well made high quality product with numerous options for fan mounting at a very reasonable price. What else can one ask for.
The "legs" were exactly what I wanted to mount the fan in a non-computer project. I also added a finger guard grill to each side and the included bolts still worked with the added depth.
Love this product, after a little alteration of the L angle pieces to work where I needed them to they have worked perfectly to this date. Used them to add some exhaust fans to pull air down the back of my computer desk so the exhausted air from PC was not being recirculated. Been running 4(2 sets) 120mm high speed fans and haven't had to tighten, or adjust any part.
