The universal receiver of my G602 mouse does not work anymore and Logitech support is refusing to provide me this part, Their response to my emails did not even make a sense. Simply asking me to buy the part from another seller? Then why did I buy this from Logitech?Their email is "Since your device is a end of manufacture product, we do not have any spare for the same. Hence request you to check with any third party reseller". Beware of this seller
