I'm not a craftsman, I share the tool with a girlfriend because the price is fierce. But I think underneath you throw money out the window. About the various applications, the other reviewers have already written. Unfortunately I have not found any application notes in the supply or on the Bosch website. The description is düftig and consists essentially of small colorful pictures. Here Bosch could still make improvements. Particularly with regard to the vibration levels.
This tool works quite differently than other tools, you have to be aware. Gently handle it, do not put on too tightly or use force. Select the proper rate of vibration. Then the Velcro hooks not melt :). The teeth of the saw blades last longer. The tool is intended for finer renovations.
The dust extractor offered I have to buy more because the tools have a recess, Duch otherwise the dust outlet upwards. The connector has 19 mm diameter. An adapter can be found on the Internet. Perhaps it need not be as original parts.
Worried you definitely soundproof headphones at the hardware store. Outside the apartment, however, is hard to hear the noise.
All in all, a strong buy recommendation, if you can get involved in the mechanism of action.
Addendum: dust extractor bought later, I can only recommend. Reduces dust by about 60-70%.
