I have a UR MX-650 along with a MRF300, the remote gets dropped by grandkids, kids, etc on a tile floor, every time it hits the floor, something inside breaks and the IR doesnt work anymore, I have had to replace it three times, any suggestions as to what can be done? I know, quit dropping the remote, but that is not an option. Is there a remote out there that will stand up to the abuse my kids and grandkids put out?
