Logitech C-BT44 USB Keyboard Receiver for EX 100, EX 110, MK300, S 510

Lost my original receiver during a move and while this didn't specifically mention my model Y-RAU7 Comfort Cordless Keyboard and Mouse set, it looked just like my old one and I took a chance. It paid off! I just needed to download the latest driver and it worked perfectly!I'm so grateful to find this, you have no idea. Can't find a comparable keyboard for less than $75. I don't have that kind of money to play around with anymore.Thank You so much!

works great!

Perfect!!!

The receiver works very well after I figured out what was up with the keyboard I paired with it. Apparently some of these keyboards can become locked. No input was coming through even though the receiver had paired with it. My keyboard is the MX3000. I had to hold cntl, alt, f12. then press the connect button on the back, then press the connect button on the receiver and then finally press escape on the keyboard. after this was done everything is great!Just mentioning it here in-case anybody else is in the same boat.As to why this wasn't mentioned front and center on logitech's site makes me wonder about those guys. I found this solution on some other site.This is probably why I found this keyboard in the thrift shop.
