I have to say that I am very disappointed in this KM combo. The item description says this:"When you're looking for the perfect companion to your flat screen, this keyboard and mouse combination has all the right qualities..."But unfortunately, I find that to be untrue - bordering on false-claims marketing. This combo has absolutely horrible range. The maximum distance away from the receiver I can use the keyboard and mouse reliably is only about 4-5 feet. Since this combo was, in fact, purchased to work with my HTPC setup, a 4-5 foot distance limit is simply not acceptable. My 8-year old Microsoft wireless combo has a range nearly 3 times farther than this Logitech KM combo. I have since put the keyboard and mouse back in the box, and they are sitting in my basement - likely never to be used again. If you want a decent wireless combo to use at your desktop computer, this one is adequate - but then again, there are plenty of adequate options when the only range you need is a few inches that cost a great deal less than this combo. So considering the price and performance of this combo, I do not think I can recommend it under any usage scenario.
