Media could not be loaded. I'm a DIY lover and I love 3D printing, so I hang things up very, very often. I used to spend so much time with a tape measure and a level plan hanging things on and this laser level has made my life so much easier and saved my job so much time. I just put the laser on a tripod and all measurements are complete. The battery life is so amazing I've used it so many times without having to charge it and on top of that it comes with an extra battery and the option to use disposable batteries to power it. I also like that the light flashes to let you know the laser is misaligned. So if I accidentally hit the tripod, it will let me know it needs adjustment.
