I like it!
I read several reviews that were almost a deterrent in my purchase. I am a Bosch believer, I have been buying Bosch for 30 years. I will agree that tools are not made like they used to be. I can see that this square may not work in bright light so that may be a consideration. All tools have limitations, so it may not work for everybody, but I like it!

It's simple and very useful device for most DIY work at home. If you need more sophisticated device for any professional installation, you may need more expensive laser level, but for any home project you don't need to look elsewhere.

I have 3 Bosh level/squares each for a specific use. Good investment at a reasonable price. Not necessarily good outside but inside it does the job well. My layouts have been accurate and there are no surprises when doing the installation after using one of the tools.

This is a good use of technology and the Bosh name does stand for quality. The recommendations came from friend and were verified because I called the CPO advisors and learned as I have in the past.

Great useful tool
I bought this tool about 3 months ago. And has made work so much easier. Snapping grids on floors has never been easier or more exact

This is the first laser level square I have used so my views might be based in inexperience. The unit incorporates bubble levels but there is no mechanism for leveling the instrument. I consider this a serious shortcoming. an examination of the unit reveals two features on the sides that were probably intended to accommodate leveling wheels.

The unit is very sensitive to surface roughness. An uneven surface will interrupt the beam, rendering it useless. I solved this problem by erecting a vertical surface at the point I wished to measure. This produces a vertical line which can be visually extended to the surface you wish to measure.

Otherwise, the product is easy to use. I haven't used the supplied adhesive to mount the unit to a non-horizontal surface so I can't comment.

Simple and effective!
Framing and speed squares have there place... and so does laser! It is like having a 30-foot square in you pocket. I was easily able to check my wood fence gate build, despite having a slight bow in the edge that would have thrown off a normal square. Great for framing walls and laying tile. I don't recommend it for vertical use- there are no screw holes and the putty requires too much tinkering.

GTL2 Horizontal Lines / Position
When using the GTL2 for horizontal lines the unit is far from being accurate.
