I have the opposite experience across probably half a dozen Logitech devices over the last decade or so. The dongle is so much more reliable and far lower latency than bluetooth. I'd take Logitech unified receiver over bluetooth all day long. I haven't had nearly as much luck with other 2.4Ghz receivers. I'm also using a RK Royal Kludge wireless keyboard and it's very particular about where the receiver is plugged in and distance from the keyboard.
