Query: Easy call Wireless keyboard

Not a very good product. The mouse is okay. The wireless keyboard needs the batteries changed about every 3 or 4 weeks. Contacted Logitech and sent me a new one. The new one did the same thing. I was sent a third one and still no difference. I gave up at that point. They send the same replacement series as the old one. They are supposed to send a different series. I now go out of my way to avoid Logitech products. I consider their products and customer service, very undesirable. Just a piece of junk.
