Keyboard is really nice. Easy to configure the special keys. I like it, but there are also things that keep annoying me. Keyboard has wireless range of about 3m, but mouse is just about reaching 2m.. No matter what I do, how I configure, how many potential interfering hardware I turn off I still get just about 2m. It is really annoying, because I'd love to lie in my bed while using keyboard and mouse, but I can only lie in the armchair which is not the same as bed :]
This has got to be one of the best bargains I've ever had! I got this for 17.99 (UK Sterling) and can't believe I've got something this good for that price!
The mouse feels "weighty" and solid, and like the cursor it's guiding, moves smoothly while the keyboard sits nice and flat, and the five thin rubber feet on its base keep it from slipping. It stays in place well when typing or gaming and doesn't slip easily.
I find I can use the mouse about 9ft from the receiver with no problems , as long as there are no obstacles/obstructions between the mouse and receiver. I haven't tried to use it further than this so I can't comment on it's maximum range. The keyboard works just as well from the same distance, and seems to be slightly more forgiving of obstacles than the mouse.
As an added bonus, the keyboard and mouse came with Duracell batteries installed, not some cheap generic brand.
It also works with Windows 7, and I didn't need to install a driver for it to work (though one is available from the Logitech website).
I bought this set to replace the cheap and nasty wired set that came with my Dell and I'm blown away! It installed with no problems apart from the supplied software not running on Windows 7 64 bit, but a quick visit to the Logitech support website, a download and everything is as it should be. The mouse is comfortable, accurate and reliable, the keyboard the same. The range of options to customise mouse and keyboard settings is more than most people would need! Buy a set today, you won't be sorry - superb value!
