This is a very handy tool and great when you can't cut a clean, straight hole. Having worked in the low voltage industry for decades, I can level a jack with just my eyesight, but from time to time I have to venture into an odd place or position that distorts my perspective. This tool takes the guesswork out of it. hit the wall and start cutting. No problem. My drywall cutout is always perfect! Get one. Be proud of your work. Work like you're doing it for Jesus Himself. This will help you improve the installation.
