Awful software, hardware and support. I have the mx master 3 and the logitech mx keys. The mx keys has had issues where the ekys will get stuck releaseing and I had to return 2 keybaords. Then after heavy use the letters/colours on the keys have been rubbed off. The mouse ios unusable if you have a mac as you can't disable smart shift and there is no way to do it without their software. This becomes an issue when using a mac device and bluetooth as the logi options software will show the device as inactive despite being connected.
