Excellent tool for fastening cable supports, studs, etc. I use it when I have big jobs. It secures very well in concrete and hollow bricks, and the work goes by quickly. You need to choose wisely the hardness of the nail you will use for the best possible result. One positive aspect is that you don't need to buy gas canisters like some other tools. It also has economical nails. The only slightly negative thing is the weight, but compared to what it offers, it is negligible.
