The nubuck eraser was meant for any kind of stain or scratch on my shoes, but only a great success with my Nike Vortex sneakers. They have a rather rough suede, my Tommy Hilfiger Boots example rather a fine. Here, however, it acted only to small repairs, major "damage" to the shoe are thus certainly not resolve. So went with small dirt stains on light gray suede quite good, on a blue (same shoe) then turn "as is" and has been roughened lighter at the appropriate places. Probably comes to on the spot. The crumbling of the eraser scary, should be known. Is finally an eraser. Does not bother me personally. For small repairs certainly useful, otherwise rather questionable. Must probably even tested and tried on each shoe. After large scratch on a black suede, then the eraser has taken on the color of the shoe and was therefore no longer so beautiful to look at and discolored when it is used again slightly to brighter suede. The color erased likely but gone. In addition, the eraser in my opinion, could be cheaper, especially since I was able to discover only in the supply that me (because not provided by Amazon) additional cost of shipping even in about 3 euros. That's apparently escaped me and funnily enough when ordering, (multiple items as ordered) was probably not so obvious. So I would buy this exact product is not necessarily repeated. Then perhaps more times right in the business (eg at Goertz), if you are traveling anyway.
