I have worked on several projects and found that my projects resulted in uneven doors, windows, etc. even with a small spirit level. This laser level is a good size and easily attaches to the wall thanks to the magnetic base. I hung some photos to power up the barn door this week and with that laser level it glowed bright red so I was able to hang my stuff with ease. I like the button at the top that lets you use either a vertical red line or a horizontal red line and of course a combination of both. Worth buying.
