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. I have had this about two weeks and one of the plastic supports that lift the rear of the key board also broke.
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. I've tried new battery's and every other thing possible until the mouse finally quit completely.
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. I have owned many Logitech wireless keyboards and have never considered any of them less than excellent. I don't know what happened with this one.The mouse is marginally better.
Excerpt: I purchased one and it suddenly stopped working after about 2 weeks. It was returned and replaced with the exact same thing. I had it for one day and it quit working. This one had to be returned also.It had been my intention to go wireless on both my keyboard and mouse. At least my old wired set up still worked. The good thing is the cooperation that I received from Staples. They are excellent to deal with. They have my business.
Summary: At least half of the time it just won't type into the computer what you have typed. You can't even delete something. It will have to go back. If it would consistently work, it would be a great product.
Excerpt: I wanted a wireless keyboard for a long time but the expense to replace a good keyboard kept me using the old keyboard (which I used for several years). When I found one on sale I went for it and I am glad I did, love it.
Summary: I needed more USB ports on my laptop for periferal devices. The MK520 system allows you to network several devices with the Logitek Unifying Receiver which only uses one USB port. I have the Keyboard, Mouse, and External Drive all networked using only one USB port.
