Are good indications, TOP function in drywall!

In Stahlbetondecken the function leaves much to be desired, since most, an error appears.
The use of brick walls was okay. There you could super test on light switches and sockets, and usually went quite well.

Really strong the GMS120 But when drywall ceiling on the top floor of our new building: there I had to look for wood bases that have been set by the drywall in order to tighten lamps in addition to the Lampenauslässen. These blocks were very tight and only one side present. Thanks to GMS, I could really do this very well find!

Too much one must certainly not expect the device, there is always to be expected with any interference, but a rough guide you get in most cases and can drill calmed down. An exception is the dry, there plays the full strength of the Bosch GMS120 from.

I forgive 4 stars and a buy recommendation. A star, I keep for myself, because I had to bear the risk even in every hole at the end)
