I could not perceive any significant differences between this and the grey Thomann-branded cloth, save for the color and size. Perhaps, the thickness is slightly different, but I am not 100% certain. Both of them are well made, except for a couple of loose threads at the corners (a weak spot of most cloths, to be honest).
Speaking of loose threads, since the majority of microfiber cloths have polyamide (a.k.a. nylon) rather than polyester stitching around the perimeter, if any loose threads poke out, I very carefully melt them with a match or a lighter to prevent the thread from unraveling any further. I ordered a couple of cloths in each color to differentiate the ones I use for cleaning guitars from the ones I use for cleaning (piano) keyboards. Practical!
