The Bosch GLM 15 is something I have wanted since it came out. Now don’t expect a lot from this tool. It doesn’t do square footage or all the other fancy things and that is why I wanted this tool. I wanted something simple, reliable and durable. Now if your looking for those fancy things, Bosch has plenty of other lasers that will meet your needs. If your looking for a digital tape measure, this is it. The unit is small which makes it easy to fit in your shirt pocket. I couldn’t ask for an easier tool. This has one red button. Push it once and you will see the bright red laser pin point your exact measurement on a continuous reading. Push it again and it will lock in your measurement. It can’t be any easier than what Bosch designed this tool for. A simple tool for taking measurements of up to 50 ft. All I can say is it’s about time someone made a nice simple measuring tool where I can just take a quick measurement and don’t have to mess with setting it up and all the different buttons.
