Logitech Wireless Solar Keyboard K750 for Mac

OK. I had a brand new Logitech K750 Keyboard for a couple of years. Loved it. Unfortunately I knocked my wine over one day on the keyboard and that was the end of it. So I have used the one that came with my Mac since. Then I saw these refurbished ones. I recalled how much I liked the solar one so I purchased the refurbished one at a reduced price. What a big mistake! I charged the Keyboard by the sunlight from the window for a couple of hours before I even turned it on. Then I paired it with the unifying receiver as standard procedure. Worked fine for a couple of minutes then died. So I tried charging it under a bright lamp for a few hours. Tried to pair it again and nothing. I checked the battery and it was full. What a piece of junk. I don't know what their process if for testing these, but they need to come up with a better process because this one was garbage. No wonder the previous owner returned it! I am very disappointed with this and will probably never order another refurbished item again on Amazon just to save a few bucks. It's not worth it.
