I am very pleased with this window. It arrived quickly and was well packaged, so there was no damage. The mineral oil coating was easily wiped off with a soft, dry microfiber cloth which left the window sparkling.  The only reason for 4 stars was because some of the solder welds aren't very neat, but not as noticeable when the window is hanging. Just be aware, the glass is mostly opaque, so if you are looking for a clear, sparkling window this is not for you. It would be great if you are looking for beauty and privacy. I would definitely recommend this lovely window.
