I will never buy from Rapoo again!
Yet more totally unrepairable land fill from yet another greedy company. I have had many Rapoo devices and all of them have proved to be flakey by one degree or another. Mice double clicking on their own, poor rubber choice that disintegrates very quickly etc.. and to top things off after spilling a little bit of cola on my expensive wireless keyboard(mouse combo) I find that it cannot be opened to clean it - not a screw in sight! All glued shut! Eventually after trying to open it, the aluminum casing became too warped to even justify a repair anymore. And as my USB slots are limited the mouse and keyboard are now land fill. Go to Hell Rapoo! This is the final straw - you masquerade as some high-flying tech company but your products are trash!! I have no idea what to recommend as another option, but I do advise anybody to avoid inferior Rapoo products!!
