Review on OMMO Self Leveling Vertical Horizontal Controller: Precise Leveling at Any Angle by Nathan Skipper

I bought this tool for projects around the house. After using the laser, it has become one of my favorite tools. I've used it to measure the flatness of the floor (both under the house in the basement and inside the house), installed plumb lines to determine placement of recessed lights, and will use it to measure the height of the floor along the determine the wall of my house to fix drainage problems. The reason I chose the OMMO laser was the price and the accessories that came with it. The remote control is a very useful accessory. Even for a moment, looking into the laser, it seemed to me that my eyes were concerned. Therefore, the remote control came in very handy to turn the laser off when I wasn't specifically evaluating the measurement results, and also to turn the laser back on when I was ready to take a measurement outside of the laser instrument. Using the remote control to turn the laser on and off will help avoid possible movement of the laser once it is in place. Another accessory I used was an adjustable table. The adjustable table was very helpful in adjusting the height of the laser along the horizontal "base" line on one of the racks in the basement under my house. The laser is bright enough. I had no problem seeing the laser lines in my house. On an overcast day outside the house I could see the line (unaided i.e. no laser detector) about 20-25 feet from the laser. (I'll wait for a slightly darker day when I measure the ground level.) The laser seemed accurate enough when I ran a basic level test. I did a level test by noting the height of a horizontal laser line on a wall in my house about 15-20 feet from the laser. Then I turned off the laser with a switch to block the pendulum and rotated the laser 180 degrees. Then I turned the laser back on and noticed that the height of the horizontal line matched the previous observation. I had a few minor criticisms that didn't affect the overall rating of the tool. First, the instructions could have been written more clearly, especially for turning on the laser. To turn the laser on for normal use, simply slide the switch on the side of the laser to the on position. This also unlocks the pendulum in the laser to deliver accurate horizontal and vertical lines. The slash (force start button) is used when angled lines (not horizontal or vertical) are needed. I also noticed that the base of the laser (or legs) didn't line up exactly with the laser lines. I tried aligning the laser to the wall at an angle, but quickly realized that the technique was imprecise and that I had to use reference marks (with masking tape markers) on opposite walls to align the laser correctly. All in all I think this is a great tool.
