Love this thing!
Color: Transparent Grey
So convenient and works well! The only wish is to make it without any wood since it’s always around water and wet but even with wood and wet no damage or issues but just don’t like wood around water. Oh, it looks great too!

Legs seem decently thick. They could be a little sturdier. The paint has stayed with no chips or flakes. Color has not faded. It sits at the perfect height for a desk. Screws and hardware do the job. No welds to speak of, everything screws together. I’ve used these for a year and a half as a school desk and has held up well. I took a sheet of project board with stain and polyurethane as my top. Works excellent
