Hot take: I hung a $6 tension rod under my kitchen sink and it fixed my whole cabinet
My kitchen cabinet was a disaster of bottles falling over every time I grabbed the dish soap. A neighbor in Dayton mentioned hanging a cheap tension rod under the sink to hold spray bottles by the neck and I figured that was a load of nonsense. It cost $6 at the hardware store, took about two minutes to twist into place, and now nothing tips over at all. I even added a second one higher up for sponges and scrub brushes. What small five dollar fix actually worked at your place when you doubted it?
