Keyboard seems fine, and the legends on the keycaps look as though they might last longer than the ones on my previous keyboard (also a Logitech). However I'm a hunt-and-peck typist, so not best qualified to comment on it from a true typist's perspective.
The M185 mouse, however, is quite unpleasant. I don't have big hands, but it feels small and awkward - and the dry, almost gritty action of the scrollwheel is verging on the nasty. It certainly isn't a patch on the larger, heavier and more ergonomic (but broken) Logitech M705 mouse that I bought it to replace.
I have marked the product as good value because the price I bought it at was substantially less than from other sellers - but I can't recommend it as a good buy on the basis of the miserable mouse.
