Summary: this product simply sucks. i cant believe this lag considering the wireless receiver is just with in 30cms from my keyboard and mouse. i just get very frustrated at the pointer movement when i move mouse. keyboard leaves out some letters while typing.
Summary: The wireless mouse and keyboard are not reliable. The devices are within two feet of the target PC but I routinely have dropped keys and untracked mouse movements. I have already stopped using the mouse because it was so frustrating to use. The keyboard is lightly used on this PC but it will get replaced, too. There's also something off about the spacing of the keys on the keyboard.
Summary: The mouse was useless. I couldn't get it to scroll with the middle wheel. It was too big for my hand. The key board was so sensitive that if I accidenly touched another key without pushing it down it would type that letter or symbol. The delete button was out of place as was the backspace button. There was a big space above the arrow buttons, which the delete and page up and down buttons should have been in. I am returning it.
Summary: After only 5 months of having this product it started to malfunction and my notebook did not recognize the mouse and keyboard. I kept attempting to get the keyboard and mouse to connect and it has caused my entire notebook keypad to stop working.
Summary: This is a nice keyboard. The only problem I have with it is that it does not have lights indicating if the "Caps Lock" button is on, and the "Num Lock" button is on. In this culture where every website has passwords that are constantly expiring and must be changed; and they require caps and lower case and numbers and special characters, we must be able to know if these keys are engaged or not; especially if, after three attempts at entering a password, we are locked out...
Summary: Keyboard is 'updating' sporadically, sometimes with in minutes of the previous 'update'. It dos not type during this time, so unless you are staring at the screen it may not be clear that the keystrokes are not being transmitted. I have had to reset more than one password due to this poor performer. Very weak product!!!
