Question: mouse battery replacement
Document: I've had this for two days now and I use both keyboard and mouse frequently and they seem to be lasting a long time, not indications of less battery life or anything. Great product. I would recommend this to anybody looking for a replacement keyboard and or mouse!
logitech is great for personal or business use. high quality performance and long range of use. long battery life as well. i won't buy any other brand. the only reason i have had to buy a replacement keyboard was due to me spilling something on my old one.bonus to buying the two - in - one package keyboard and mouse is that they plug into and use only one USB port.
This MK320 a replacement direct from Logitech. I had the previous model and the foot broke on the keyboard. They kindly replaced the whole keyboard/mouse combo with a new set. That was wonderful, but the new mouse eats up the battery in a few days. The older version mouse battery lasted for months. I'm not happy with the battery life at all. Everything else works fine.
I have had this wireless keyboard and mouse for about a month with no problems. I purchased the Logitech MK320 wireless keyboard and mouse as a replacement for my HP Pavilion Desktop computer's wireless keyboard & mouse. It truely was plug and play, all I had to do for setup is plug in the USB receiver and turn on the mouse and keyboard, pull the tape tabs that isolated the battery, and I was off and running. Yes, the batteries were included.
I am very particular about the keyboard and mouse. I use the function keys a lot (F1 to F12). Many keyboards have small or harder function keys. I do not like a small mouse. I want to mouse to fill my palm. This particular combination had the right keyboard and mouse size for me.I had a problem with the mouse because there was white powder near the battery terminals. So I called logitech support and they said they would send me a replacement.
This keyboard and wireless mouse were a replacement for one that had been worn out. It is perfect. Works GREAT. I'd highly recommend to anyone looking for a wireless keyboard/mouse.
Logitech has great products. Never disappoints. Well made and can be relied on to always work without problems. Excellent replacement keyboard and mouse for my computer.
This key board works great and windows 7 saw it right away .a great replacement for a corded keyboard mouse combo.Works well and windows sees it.
Instead, you have to ship the mouse and keyboard back to them to obtain an entirely new set. They did not charge me for the replacement set. A seemingly very strange and inefficient policy for both parties.And my experience with their customer service was very frustrating.
Bought this as a replacement keyboard. Easy to set up, easy to use. Like the idea of a USB stick rather than the older USB connection with half mouse. Very quiet keys. Can't beat it at this price! Came very quickly, packaged well. No problems at all.
Answer: It hasn't been an issue.
