I use these tools a lot, for me it is a close tie between this tool an impact. The weakest by far is the M18 Multi-tool, poor design, manufacture, excessive noise (this gets much worse as you the tool), and overall performance. I have many M18 (and M12) tools and many that have been upgraded to Fuel. I know that I am bumping an old thread, but hope to get generate some interest in a M18 multi-tool redesign.
