I took it about 5 years ago for a small cosmetic repair in odnushka for 3000 rubles. Perforated household green. After that, he took up tightly on kolyma on an electrician. I don’t remember the smell of plastic, and not the point. in general, I calmly survived the grooving with a 20 mm meter drill, 68 mm socket boxes in 3 odnushki with sockets where it is possible and 2 three-wire ropes + along the way there were basements attics and other little things without socket boxes, except for the first apartment there were panel and a monolith. the ratchet worked perfectly when casting only when really needed. unlike makita of the same power. The power was about 3 J, it’s a little inconvenient to drill for a take-off, on the other side of the wall large pieces fall off. Recently, almost died, I think something fell apart in the gear judging by the sound. but in general he paid for himself several times. I also bought a hammer only more powerful, so that the socket would drill faster, for 3 years of warranty it would definitely pay for itself. makits of this kind are worth tens of thousands and I don’t know if they will pay for themselves.
Minuses
the impact power when drilling through, large pieces of the wall fly off from the back side, it’s heavy, but if you are a man weighing 80 kg it doesn’t matter. It is difficult to find parts and service where they do inexpensively.
