We are renovating our new apartment and of its predecessors are some pretty cruel wallpapers left. I had first tried to soften the wallpaper with wallpaper strippers from the hardware store and then scrape what a lot of work was, took an incredibly long time and has done virtually nothing in particularly good holding age-old wallpaper on plasterboard wall. With the steam wallpaper strippers, however the wallpaper were disposed of super fast and well from the concrete walls and the extremely stuck on the plasterboard wall has can be solved also. The box was indeed partially damaged, but a lot less than it would have been possible with any other method. I highly recommend this device only to anyone, the value for money is great, you save time and nerves.
