Negative Positive
Title: Didn't work for me.
Review: I bought this keyboard and mouse directly from Lenovo with an X61 with Ultrabase and monitor. The mouse worked but the keyboard did not. After 2 replacement keyboards Lenovo agreed, reluctantly, to allow a return with refund. There are no instructions with the hardware describing how to set up the keyboard. The detailed instructions I got from the support desk at Lenovo did not work either.
Is the review positive or negative?
