At first I was sceptical to use these cotton pads because they felt really thin and flimsy. But once I used them, I fell in love with them immediately. The thinness of the pads allow for way less toner usage, effectively saving your toner. My favourite tip is to apply slightly more toner and squeeze the cotton pad to help it soak the pad fully. For 160 pcs and £5, you can't go wrong on this one. It lasted me nearly 3 months of daily usage (1 in the morning and 1 at night). Easily a winner in my book.
