Good deal, bought for home. The level beam, like a rangefinder, is clearly visible in a room with room light. In the bright sun from the window, it is no longer so cool to see. The vertical goes to the floor and ceiling. With a standard height of the beams, it covers the height of the wall with a decent margin. Shoots level calmly at 8 meters, did not check at long distances. All in all, a great set for the money.
