Accurate, very easy to use.

Amazon is lumping the reviews for the GLM15 ("Basic Unit") and GLM20 together. This review is for the GLM20.
IN USE: This laser measure is very simple to use: simply turn it on and it gives real-time measurements. Press the button once (it only has one button) and it will hold that measurement. Press the button again, and it will give new real-time measurements while still displaying the previous measurement. I prefer this to my Stanley laser measure, which requires you to press the button twice to take a measurement. The measurements are taken from the rear edge of the tool so, for example, you can hold it against a wall and measure the distance to another wall.
ACCURACY: I tested it at 2 feet and 6 feet against a tape measure, and it was right on the button both times. I also tested it against itself, taking repeated measurements of the same distance, and it gave identical results every time.
ERGONOMICS: This Bosch is smaller and lighter than my Stanley, and it fits nicely in the hand. See pic for sizing.
OTHER FEATURES: auto shut-off (after five minutes); switchable unit of measure (feet & inches, inches only, or meters); backlit display; batteries included.
CONS: This Bosch doesn't do any calculations (area, volume, differences between distances, etc.). If you want those features, you'll have to look elsewhere.
