I got this tool for work as an electrician's assistant. This involves cutting a lot of 12-3 Romex. In theory, covers on for me. The time it takes to switch tools is worth it to keep my hands from getting chewed up.
The truth is I haven't used it enough to say for certain.
I can say that the time it takes to switch between tools won't matter too much since most of what I do is done in stages. Do a bunch of long wire runs. Hammer in boxes (not with this tool, obviously), feed wires into boxes, strip wires. So it's a lot of using one tool, then switching and using another tool for a good amount of time.
