NONE

Does not work half the time take a battle to get it to work I will never buy another linkword product again

cheap

You get what you pay for" is an understatement here ; So cheap not worth shipping for RMA, but this product is worthless JUNK. I've built hundreds of computers...trust me...DO NOT BUY THIS

Um...I don't want to lie

There is absolutely NO range! I literally have to have the reciever right next to the mouse to get it to work! Even then, it lags! I couldn't imagine this even getting out of the testing stage unless they didn't test it

It's cheap

You get what you pay for. Seems like a good product at first, with all those hot buttons, but looks can be deceiving. I have to re-connect the mouse every time the mouse is idle for more than 5 minutes, the keyboard too but not as often

Real bad lag between keystroke and the character appearing on the screen, constantly loses connection with the reciever and has to be reset.
