HP 965 Ergonomic Wireless Keyboard for business

This was a very promising keyboard, my beloved Microsoft keyboard after over 15 years of being faithful finally died when a few of the keys stopped working. I purchased this HP keyboard because it is very promising. I do not like that the keypad is a separate item. I would prefer them to be together, but now that my keyboard has died, I can use the keypad. I purchased two of these last year and I initially loved the keyboard, it is comfortable and works great. And then 1 year into use, the keyboard just stopped working, but the keypad works. I replaced the batteries still does not work. Went through multiple driver updates and troubleshooting on 3 different computers, it is dead. So I brought out keyboard #2 and it works great. I decided to purchase another 2 since they were on sale half the price of what I paid. BOTH arrived with keyboards not working, but keypad is fine! Not sure what you will get... don't purchase for only 1 year use! Or getting brand new keyboards that don't function at all.
