This VEVOR laser level, 100ft, Self Leveling Manual Green 3 x 360° Cross 16 Line Laser, is just an awesome tool at an incredible price. It comes with a molded plastic storage case; the laser level; one battery pack; an adjustable platform; an alignment card; and a USB-C cable to charge the battery. The battery pack is 3.7v, 5200mAh. The instruction book is very basic, but it covers all you need to know to use the laser level. If you're not sure, there a lot of videos online (I watched one first). The laser has horizontal and vertical lines that can be turned on together or by itself. The laser level has a self-leveling mode where it works within 3+/- 1 degrees. If it is out of this range, the laser will flash and beep. The beams can be set dimmer by pressing the H button and turned brighter by pressing the V button. I used the laser to shoot lines across the bottom of a rocker who's base had come loose. I set up the laser using the adjustable platform. It worked but I think next time, I'll use my camera tripod. The laser lines worked perfectly to show me where to drill for reinforcement screws. The laser made the project so much easier. I have to say this is a great addition to any DIY'ers toolkit. It is one tool, when you need it, it proves its invaluable. A great tool for an incredible price.
