Logitech K850 Wireless Bluetooth Keyboard

Updated: Dropped rating to 1 star. Really tried with the refurb but I can't get it to feel right. Removed all the keycaps to clean everything so I assume it's an issue with the membrane. After cleaning, it's better than as it arrived but still no where near the responsiveness as my other K850. Some of the keys feel mostly normal while others feel like they're pushing through syrup. Decided to just return this and get the new combo with mouse. Original Review: The keyboard itself is great if you have a need to use with multiple devices. The renewed quality however is not consistent. Keyboard came with several keys that were sticky or non-responsive. That was replaced but the replacement was still somewhat sticky. Popping the caps off then putting them back on made it better but still doesn't feel quite right. Unfortunately I haven't been able to find this keyboard new without a mouse combo costing double the refurb price so I'll just deal with the slight stickiness and maybe try cleaning the keys again.
