The most important factor that makes laser level is the good accuracy. for example, the top quality laser levels has accuracy of around -+1.5Xm at 30 m distance and a good quality laser level will have at least -+3Xm. the accuracy rating will decide how much precise the laser level is.afe. The most important feature of a good laser level is that the laser level should be safe for use. The laser beam of the tool not only can affect the user but it can also bring certain damage to the passersby around. A good laser level should not cause any such damage to both.
