Bosch paint spray systems - experiences?

Hi,
we are currently considering whether to do painting work more on our own or to outsource it, and are thinking about getting a Bosch paint spraying system.
Does anyone have experience using it (preferably the somewhat more expensive 5000 system) with dispersion paints?
In the reviews, you read everything. From "great device" to "the paint mist spreads everywhere" and "the airflow blows all the foil/fleece around the entire room."
So opinions range from "huge work simplification" to "complete waste of money." Some write "okay for one room, I wouldn't use it for a whole house," others say "not worth it for one room, but more so for a whole house." ....
Can someone shed some light on this?

I can't say anything about Bosch. But: We (or rather my wife) plastered the entire house with a Wagner W890 paint spraying system and tinted Knauf Easyputz 0.50 mm on Q2 plaster.

Yes, you have to tape off properly, but not much happens during the shell construction phase. I don't know how it works with dispersion paint. Normal wood glaze definitely works.
