I have few complaints about the keyboard. It seems to work reliably an, though there is a slight lag in typing. However, the mouse does not work. It initially worked but would at times stop connecting. After a days use, it stopped working entirely, even though I replaced the batteries. The problem is clearly with the mouse since the batteries are brand new (and work in other devices), and the keyboard is still working, indicating that the USB receiver works. I should have gone with my better instincts and bought a mouse with a cable. I am using a mid-2012 macbook pro running OS Mojave.
