Review on Full-Sized Wireless Keyboard and Mouse Combo with Typewriter Flexible Keys and Auto Sleep - 2.4GHz Compatible with Windows 7/8/10, Cute Design KS66-2 by Keisuke Shimizu ᠌

I've been using this set for about 6 years. For the third year, the mouse began to fail: first the middle click broke, then the wheel began to sink, then the right mouse button fell off (you have to press it hard to get the long-awaited click). Unfortunately, it turned out that it would not be possible to buy another mouse separately, which would work from the same receiver. From the very beginning of use, sometimes the kit lost a signal from the receiver. This is due either to the frequencies of other devices in the room, or simply something was blocking the signal. It is treated by sticking the receiver into a USB extension cable. Personally, I connected to a stationary keyboard that has a USB hub, and the problem was resolved.
