Generally good level, but the beam line is wide, about 0.5 cm at a distance of one and a half meters. I don't think it's suitable for professionals. And the tripod can only be raised a meter. If the device is placed on the floor, then it shows a horizontal line at a height of 11cm. The beam is bright enough in the apartment, I don’t know how it will be in the sun. The beep is not so loud, the sound cannot be turned off. For household needs, the appliance is more than!
