Query: Cheap... Bad welds...

It works to raise your handlebars but it looks like it cost about a dollar to make! The welds look like they were done in a high school metal shop. It could be really nice if the welds were smooth and the chrome was heavier. I would be willing to pay more for a better product. However, there isn't a lot of 21.1 options available so the choices are limited.
