Review on Wireless Logitech MK240 Nano Keyboard 920-008212 with Nano Receiver by Vassil Botusharov ᠌

I compared it with the cheapest kits from SmartBuy, everything is fine in this regard. 10 meters - there is a signal and quite confident. Some pros: Small in size. Affordable. Appearance, different colors. It is a pity that blue colors are not imported to us. Cons below: The most basic is the range, or rather the lack of signal range already starting from 2-3 meters. Those. even in the room from the sofa, communication with the transmitter is lost, which is plugged into the port on the front side of the system unit. Either there is no connection at all, or there is a noticeable delay when controlling the mouse or entering characters from the keyboard. At a distance of 5-10 meters there is no signal at all. Therefore, in large rooms, meeting rooms, etc. this kit is useless. I tried more expensive (~ 6000) Logitech kits - the problem with them is still the same. Perhaps this is due to frequencies that may partially overlap with WiFi, but this is not accurate :)
