I have had several of these brushes. The 2.7 inch brush is too big for most wine glasses. But no worry. You can cut the plastic scrubber assemblies to the size you want. I used regular scissors to cut the plastic on all sides with a radius of about 0.3". , leaving a scrubber about 2.1" in diameter. It fits perfectly in most wine glasses. My largest The problem is that over time the metal bracket on the handle begins to rust and deform, gradually the steel metal lever softens and then breaks, you need to buy a new one every 1-2 years.
