I went in with the intention of buying a variety of cloths, but after speaking with Luke, and getting a better understanding of what I actually needed, I went with 2 40x40 suede cloths.
I use them for polishing my computer screens, phones, camera lens and reading glasses. when its just finger prints and a few marks, the suede cloths are doing way better than the ordinary microfibre cloths I've been using (which would just smear the prints and oils on the glasses or screens).
I like it so much, its the first one I reach for now. My other microfiber cloths are feeling rejected. lol.
I will be back for the windscreen ones next.
