I wish I had researched more about Logitech's wireless products and just bought a separate keyboard and mouse, both of which were "Unified Receiver Compatible". cheap and cumbersome to use. The ergonomic curves seem more like a marketing gimmick than anything else. It's also an older keyboard model compared to the newer mouse model that comes with it, and requires two different programs downloaded from Logitech's website to program the customization features for each. Also, sometimes the mouse functions stop working and I have to go back and reset them. The mouse is also a newer, modified version of the original M705 mouse. Research shows that reviewers claim that the original version is much better than the one included in this pack.
