What were the first impressions of your unit?

The laser level – exactly what you expect from a Bosch Professional object – is very well done and difficult.

How easy was the device to use?

After reading the instrument’s instructions, I noticed that the laser level was relatively easy to use in its most basic format. I was much more comfortable with what I did after many times using it, just like other instruments.

I had to mount a variety of sockets, switches, and other outlets, all at various heights, in plasterboard walls, so for this job, the laser level was perfect.

Seeing the green laser was really simple and I personally found that it was more ideal for my eyes than the red lasers I used before.
