Query: 6 months then would not work

This keyboard was great for 6 months, then the letter B stopped working. The keyboard was not abused, nothing was spilled on it, and it was not banged on or mistreated. It worked well the night before then after sitting by itself undisturbed on the desk overnight(I don't have children and my wife has her own computer) I used it the next morning and the letter B was nonfunctional. Tried everything and it would not work. If you think the price is fair for a good 6 months of use then this keyboard is for you.
