Logitech MX Mechanical Mini Bluetooth Keyboard

Update 2/27/23 I would give this keyboard ZERO stars if I could. The backlight functionality is useless. It constantly goes to sleep, constantly resets your brightness settings, etc. I spend too much time each day re-adjusting this thing. They should never have given this keyboard backlights if they insist on implementing it this way. Horrible. Just horrible. ------------------------------------------------- This is a decent mechanical keyboard (I got the clicky version) I like the look and feel of it and it types well enough. I do not like the fact that the backlight settings reset to default if you turn the keyboard off and on, reboot your PC, wake your PC from sleep, etc. Every time this happens you must adjust your backlight brightness and effects to whatever you had it set to. Very, very, very annoying. They also set the fn F1 and fn F2 keys to decrease and increase brightness which on a PC is a fairly useless feature, in my opinion. Most folks set their brightness on their PC once and then forget it. These keys could have been set to something else like sleep mode or email app, etc. You can re-assign those two keys so it's not a deal breaker. There is also a lock PC button on the upper right corner which is great unless you use the numpad a lot. I've accidentally hit the lock button a few times already. But I'm sure I'll get used to it as the layout is slightly different than the keyboard I replaced it with. Overall a good keyboard with a couple annoying aspects. I'm sure they can fix the backlight issues with a software update. The ability to switch between multiple devices is a nice feature and works as described. UPDATE 12/22/22 After speaking with Logitech support they suggested replacing the keyboard for the backlight levels resetting issue. I just got the replacement today and the backlight levels still reset to default after turning the keyboard off and on or restarting the PC. Since I Logitech support suggested it was defective I thought there was a chance but in retrospect I think they were just passing the buck. I have a feeling the backlight is acting as designed. I even posted TWO questions to the Amazon listing for this keyboard and both were immediately answered by Logitech support saying "contact Logitech support" and then they deleted my question. I was curious if other users had this same issue. THEN I would have known that it's acting as designed instead of wasting time with an unnecessary product exchange. I like the keyboard except for that one thing and Logitech could easily solve this with a firmware update. But based on other reviews for their keyboards it sounds like they don't listen to their users.. UPDATE 2/4/23 After a couple updates the backlight issue still persists. Several times throughout the day I have to increase the backlight to maximum brightness. It is ridiculous that they even give you the ability to change brightness if it's just going to reset in a couple hours. Also, the activity timeout is way too short. If you stop typing and take your hands away from the keyboard it turns the backlight off in 5 seconds. Once you start typing (not before) the backlight turns on. They claim this has an ambient sensor (doubtful) and a motion sensor. The motion sensor does not work when it's sleeping, you have to touch the keyboard (actually you have to touch part of the metal plate under the keys, to get the backlights to come on. This would appear to be a capacitive sensor rather than motion. Regardless LogiTech doesn't care about any of this and has no intention to resolve. Once their products are out the door you can forget about meaningful firmware updates to fix issues. Probably the last Logitech keyboard I'll buy based on this experience.
