Hmm, isn't Lenovo making/branding those these days? Atleast the one I bough(10 or 15€ for keyboard and mouse when I didn't know better and thought that Lenovo was a quality maker on full range...) looks pretty much same apart from it's black and there is Lenovo logo on it...
Average keyboard, still might be somewhat sturdy as our school have lot of these and don't feel too bad, unlike Cherry G83-6344 which I came across and it was horrible...
