Logitech MK850 Performance Wireless Combo

I have been a long time buyer of logitech product and never have any issue with any other products, in fact they're normally my go to for these products, but this one is a major disappointment. The keyboard and mouse disconnect frequently when your using them, more then enough to drive you completely insane. Doesn't mater if you're using the receiver it comes with or the built in blue tooth, in fact the blue tooth is even worse making the mouse cursor skip/jump across the screen. When you check in the Logi options + app, it says that the device is "inactive" even though you are using the device at that time. Would not buy this again nor recommend that anyone else does.
