I often change between the normal glass cover on a pan and a spatter screen, and I really got tired of having to find space on the counters when putting one down temporarily.
Since I only use my front 2 burners, and I have the rectangular cast iron pancake / bacon thing for the grates that came with my oven along the back edge of the burners, I wanted to find something I could put on that so things would not be near the heat.
This was perfect. Fits easily under the microwave range hood, and lets me put my items in it so they run parallel to the front of the stove, and I can pull them out from either side. Keeps things instantly available without wasting an inch of counter space.
No assembly required, it ships fully assembled so just pull out of the box and put where you want it, and you're up and running.
