Review on Enhanced Horizontal Visibility: BOAYAL Leveling Construction Tool by Jose Muenzen

This is a very nice and handy product. The laser is very bright and clear. Just switch from the dashed line to the vertical and then to the horizontal line. Self-levelling and comes with a mounting bracket that can be attached to an object such as a pole, wall or stand to achieve the required height. If it's not aligned, the button on top will flash red and turn green when it's aligned. Very simple and easy to use.
