Laser Level, RockSeed Cross Line Laser with Self-Leveling, Vertical and Horizontal Line, Rotatable 360 Degree, Carrying Pouch, Battery Included (Green)

Includes self leveling and non self leveling for a complete functional package at a fraction of the cost. Build quality is okay and actually perfect for an occasional user vs a pro daily user. To get this functionality from a Bosch you'll be paying 6X the cost. Accuracy is perfect for a 30x30 room. I have a pair of Greens and Reds for use with a trackcar wheel alignment project for which I need the Non-Self-Leveling function. This way I can compare the rear (green) and front (red) adjustments relative to one another without self-leveling throwing me off. But you do have to pre-level and lock all four equally before starting.

This tool is a huge timesaver and worth every penny. I attached it to a telescoping camera tripod (tool comes with mounting holes) and used it to install over 20 shelves of various sizes on 6 walls in my basement entertainment area. It was so fast lining up a shelf while on a ladder. I wasn’t constantly reaching for a level to check for level and plumb. This tool’s finest moment was while putting multiple small shelves that were “stacked” on top of each other up both walls of an inside corner. Lining up all the shelf brackets vertically up both walls so they were perfectly level was actually enjoyable because it was so easy while standing on a ladder. All the shelves came out perfect and looked seamless from wall to wall. Using this Lazer level was so much faster than putting a level on the wall and putting tick marks where each screw and shelf bracket would go. Easily saved me hours of time. Very easy to accomplish with this tool with the illuminated level and plumb lines. I used it to install the shelves, sconces, dartboard, big screen tv, electric wall mounted fireplace and wall cabinets. I can assure you everything in this room is level and plumb, lol. I use it as much as a conventional level now. I mounted it to a 5 foot telescopic camera tripod. This helped a ton because it kept the lazer level in one spot and all I needed to do was swivel it to the wall I was working on at that time.

Works great for what I do. Level is good. Build quality is sturdy. Readability inside is perfect, but for outdoors or in bright light, might be difficult to see.Overall very good for the money. Obviously if your job depends on it, you'll want a better one, but for light use, it's perfect

Great for the price. Easy to use.

This works fine. I thought this would be a little more sturdy but I feel like the laser is extra sensitive and is always shaky. I would spend more next time but this will work.

Obviously a Bosch knock-off, at a 1/4 of the cost. I've had very good luck with it. I double check it occasionally with a quality level and its always spot on. I use it on a camera tripod for cabinet installs. My co-workers Bosch unit seems much harder to setup, very finicky. I'm happy with this one.

This is perfect to ensure picture hanging is done perfectly. Have used it for other applications too - anything that requires being level or plumb is a good use.

Seems to work great.
