Good Day, This email is to express my dissatisfaction towards my newly purchased keyboard/mouse combo set. This item was given time as a christmas present. Receipt attached. The product worked well until a week ago when I was tying a letter and the P key began to repeat itself, the the A and S key began doing the same thing. Now the space bar is doing the same thing. We have use a whole air can blowing through each key but the result is still the same. The KEYBOARD S/N #2039SY08LQR8. the mouse seems to be working properly.
