Summary: I thought my issue was with 2.4GHz frequency interference, except it locks up instead of lagging badly. I replaced the battery the first time and then it froze a couple of days later. I tried new drivers, reinstall drivers, install Logitech software, different USB ports, even usb 3 ports, etc.
Summary: I am a big fan of Logitech products and have used them for years, but in this case I would move on to the next product. A quick google search will tell you that numerous people have the same issue with this combo and Logitech has never addressed it.
Pros: Decent appearance, build quality is on par with other Logitech products. Nice keys and mouse is a decent size unlike some of the other combos.
Cons: This combo works on the 2.4ghz band and it has constant interference with other electronics such as phones and wi-fi signals. I have purchased 6+ of this combo for the office only to find out they all have interference issues and constantly lag and stutter. I am 2 feet from the usb reciever and t...
Excerpt: The mouse has worked fine, has a good feel and I like it. The key board works fine when it functions. The problem is that it will sporadically stop working resulting in missed letters or numbers. Keep hitting a button and it will be nothing then every thing you hit. This is frustrating.
Summary: I bought this keyboard package just 3 months ago from Amazon and it has been horrible. Keyboard has be repeatedly pressed to get it to work, the mouse has quit working many times and if you tapped it on your hand it would come back to life.
Excerpt: This is the worst keyboard I have ever owned. Its space key is non-functional for anything short of a sledgehammer of a thumb. The zero on the keypad is the same. I have occasional delays of 5-10 seconds before keystrokes register on screen for all keys.
Summary: Tried putting the usb receiver it various ports. Turning all radio devices off. Switching out the battery. Repairing device and drivers. Nothing works.
Cons: This combo brings about the perfect reason why NOT to buy a wireless - the delay issue. - Keyboard randomly stops accepting inputs for a few seconds. - Bad delay with the keyboard input. - Mouse stops functioning until i take the battery out. - Mouse skips pixels at random.
Summary: Have used Logitech for years and never had a problem. Because of this experience, I am no longer a loyal Logitech customer. The kybd & mouse are being returned, so I will not have owned them long enough to comment on battery life.
Pros: Got it for a very good price (not from NE). Plug 'n' Play. Decent keyboard & mouse feel.
Cons: Keyboard skips and lags frequently, and no, it is not because I just "woke it up." Does it in the middle of a conversation. Mouse intermittent too. Keyboard and mouse are within 3 ft of the dongle on the back of my computer. Changing batteries didn't help. No utilities or software of any kind. Co...
