Review on ECHOGEAR 10U Open Frame Rack - Wall Mountable Heavy Duty 4 Post Design for Networking & AV Gear - Includes 2 Vented Shelves & Mounting Hardware by Marcus Morgan

This is a sturdy shelf with precise holes and screw placement. Not everything needs to be adjusted freely before tightening; he collects squarely. The shelves are thicker compared to some brands and fit most devices well. I wish one of the shelves was deeper; I would happily pay more for a 4 point alternative. Some reviews say the mounting holes don't line up, but they are there. Network racks have variable hole spacing; they are grouped into 3 groups of holes with an interval of 0.625 and 0.5 between these groups. You just can't install shelves at any height you choose. I wish they had designed the wall mount holes with a little more lateral adjustment as my wall studs are not particularly 16" on center. But overall good value for the shipping weight.
