A positive feature is: She has a beautiful soft start, seems stable and not too cheap and also has a decent weight, the laser is ne good thing and lit also quite far. An additional small pulley is installed on the device, which makes it easier to glide over the ground a bit. My industrial vacuum cleaners fitted straight into the provided receptacle. When she pulls back makes them perfectly clean slots and remains quiet and safe to the wall or lying on the ground (but is not in the sense of the builder eigntlich!)
Unfortunately negative falls on: The connection cable could be one meter longer (to my mind). With a ceiling height of 2.50 m, the cable does not reach to the earth, because I have it connected directly to the cable drum with vacuum cleaner. (Well, I could have done even an extension cord between now!)
Furthermore, the wall chaser allows bad push forward. They stuck fast and always wants to run away from the wall, so you have it "really" grab fixed! (My application had masonry walls)
You should have a strong industrial vacuum cleaners hang around at least be able to suck the coarsest, otherwise one is quite fast in dust fog. Dust mask, safety glasses and ear plugs should be stehts there!
It remains to be seen whether they survived the entire house renovation!
My conclusion: For small renovations where you have to pull a few times slots here and there it is suitable. For continuous use rather less, for the simple reason already that you can only use the machine backward best.
Therefore, I forgive only 3 stars.
I would buy me again but for the price!
