green is more visible with the same energy output, red has all the qualities one could wish for like more expensive devices. The 3-axis unit has the basic controls that we see on most of these imports. What sets it apart is the incredibly low floor stand! Ideal for leveling floors! Damn this pod alone is worth the price of the level, very well made, easy to set up, should give it 5 stars just for adding the pod. Recommended!
