Needed to replace a wallpaper brush and have never tried these before, but seen demos on You Tube. Every bit as good as I needed. Easy to handle, flattens the paper evenly, removes bubbles to the edges really well. Better than a brush for me.
Really great on inside corners without ripping the paper. Would recommend.
Having used this several times, I would like to add the comment that on non vinyl finishes (ie more like old fashioned paper) be careful as vigorous use will rip paper soaked in paste.
