The brand is one of the reasons people buy Milwaukee Tools, but they are still one of the big brands on job sites for the simple reason that they work, they work very well and the warranty on many of them is 5 years. They make no secret that they're made in China- would you have them change the name when it has been established for so long? I would bet that Milwaukee sells far more items than JBL and the items JBL makes have far fewer parts, most of which never move once the thing has been assembled. I don't know if you have used any Milwaukee tools, but my 18V NiCd hammer drills are from 2005 and 2007, used extensively in all modes (driver, drill and hammer drill)- I replaced one set of brushes and the chuck on the first one and neither part failure was their fault. The newer of the two has never needed anything other than new batteries and that one has seen 99% of my drill use since I bought it in '07.
As the executive said, Milwaukee Electric Tool would have closed if they hadn't sold the company because it's absolutely impossible to make those products in the US and compete with the foreign brands although their designs come from the Brookfield facility. That said, the owners did a lot of work (remodel, expansion) on the design/engineering/test/service facility here, put up another building across the street and are planning another in the near future, so their investment isn't only in Asia.
How would a 'top of the line' brand make something better and what would they call it? They have the best batteries and when they came out with their first 28V Lithium Ion batteries, I saw the charge indicator and asked someone in the repair store if they had a way to track average & peak current, temperature, etc and he confirmed that and my question about whether they were seeing a huge number of repairs that were caused by abuse.
I knew a guy who was a design engineer for MKE Tool and the day I picked up my first hammer drill from him, I saw two 2x12 boards leaning against the building with fairly large holes- I counted 72 and he said they used one of the 2-9/16" self boring bits with a 28V drill with one battery to make all of the holes.
A YouTuber who goes by 'The Den Of Tools' has a post that shows which companies make what power tools and several others post tests comparing brands- the tests aren't scientific, but they could be seen as 'typical' WRT how tools are used correctly vs incorrectly. Some of these tests are destructive, but still informative.
