I recently ordered this keyboard by accident realizing that I meant to order the LK67, and to request an order cancellation it was as simple as the "chat with us" feature, I informed the support person of my mistake and asked if it would be possible to cancel the order. Within minutes I had received a full refund and was sent on my way. Although I did not test this product I can give you the piece of mind that every consumer wants when buying a product. I give these 5 stars to the customer support people over at GamaKay, because that is service right there.
