Totally transformed the kitchen in my rented townhouse in 2-3 hours without any help. Very forgiving product for mistakes, repositioning, etc. Just a note that if you will be tiling up to an open wall end (or a pass-through like me) you will need some kind of edging as it will be totally impossible to make the files flush visually. I used a 1/2 inch width of cheap white wooden molding around the pass through and it looks wonderful.
