I just got my Airwolf back from it's first maintenance. In late August the UEL started flashing, so I took it to my local AD for maintenance. A week later, they told me the maintenance would be $150, and an additional, optional, polishing would be $180. I opted not to get the polishing, since it wasn't in such bad shape that I could justify the cost (especially to my wife).
Three weeks later the watch was back at my local AD, and even though I didn't get the polishing, the watch sure looks like new! So for my first experience with BUSA outside of purchasing the watch, I am very pleased.
The container that it was shipped back in:

Inside the container, a nice microfiber cloth:

There she is!

Nice and cleaned, desk scratches are all gone:
