I heartily endorse Milwaukee cordless tools. I started with the M12 series of tools and found them to be lightweight and surprisingly powerful.
Then I discovered the M18 tools had more capability with a small weight penalty.
I use both lineups and have accumulated quite a collection of cordless tools, to include a table saw, chop saw, chainsaw, cordless router, string trimmer, and tire inflator. I’m amazed at the power of these tools, they perform just as well as their corded counterparts.
I get Milwaukee’s emails, and they are always coming out with new stuff. There’s an M18 compressor coming. I’m sure I’m going to investigate that as soon as they hit the shelves.
