I had previously purchased a clamp on set of metal mesh drawers, but the back was not supported and the whole thing was tilted nearly 45*. I knew I needed something more stable that would screw into my standing desk, but I also couldn't afford $80-90.Then I found this.I lost the template while I was unpacking it (which I found after I finish installing, of course), so I put the drawers into the side pieces, marked the bottom of my desk with a sharpie, drilled the pilot holes, and installed the drawers in about ten minutes. The screws are VERY close to the "walls" that hold the drawers, so you'll need a drill extender or to use a long screwdriver to get the best install.**Easy installation, very sturdy, fits everything I need to have in the drawers, and takes up very little room. Looks like it was intended to be part of the desk from the start. I'm very glad I paid for this myself, because I will absolutely be taking it with me when I change positions.
