Wonderful feel to the keyboard and the mouse. Its a membrane keyboard, so it quieter than most. If you are a gamer looking for the loud click clack of the keys. this is not the keyboard for you. Mouse feels very nice in your hand and i have no problems with the connectivity. Headset can be improve, do not have the best sound quality but the microphone is actually pretty decent. The only problem i have with this keyboard is due to the breathing mouse my computer refuses to completely go into sleep mode, unless I manually put it in myself. It will have my monitor off and seems to be in sleep mode, but the LED lights inside my computer and the lights on the keyboard/mouse stay on. If I let this continue for longer than an hour, my computer refuses to turn on and i must let it sit while off for over an hour before it lets me turn it back on. Upon turning on, a message comes up saying an unexpected system failure happened.
