Point laser levels are levels that make you able to simply transfer a laser spot or more to the wall or other surfaces by moving the head of the laser. They are very easy to set up and using them is also very simple. Point laser levels are cheaper due to being less sophisticated than other types of laser levels. As they are less versatile they are good choices for periodic use at home rather than continuous use on site where a more fully featured device might be needed which are not as cheap. They used in leveling things like a new socket to line up with the existing sockets and with some models transferring points from floors to ceilings is possible.
