This "spirit level" makes it really fun to build. The construction projects align horizontally and vertically on the red laser line is much easier than it was with the good old spirit level. The only thing that I think is not really clearly mentions the Tastache that one technical reasons, the laser line can not move vertically by gently tilting the cross line laser. To do that, you have to position the entire laser higher or lower. The best that goes naturally with a photo tripod. If the tripod but can not be set high or low enough, you have it on chair legs or fix the like which is sometimes a bit fiddly.
