Great tool for installing speakers indoors or outdoors with 4-wire cable. composite wires. Easy to use, I practiced cutting, especially spiral cutting, first on a piece of discarded 4-strand wire, and it also helped me find the right depth of cut. Just watch the video. The only downside is that it's a bit pricey for those who only do a few DIY projects, it's really a tool for professionals who do a lot of setups.
