First time i'd bought a wireless Keyboard mouse combo...and wasn't sure what expect. I needn't be concerned....it's a doddle to set up, just plug the uSB wireless received in the PC...pull out the battery tabs, swiched them on..and away you go...don't need to do anything else. I'm always seemingly the last to catch up with any latest trends..but a wireless keyboard and mouse, makes sense. No more wires getting in the way, and i can put them anywhere i like (within receiver range of course)...and type away. Construction wise...both keyboard and mouse feels robust & durable enough, but i've not long had them. The only minor quibble i have with the keyboard, is that some of the keys are in different places to where they were on my old keyboard, so i do accidently press the wrong ones from time to time, but i'll get used to the new arrangement soon enough. All in all..i'm impressed.
