We suggest you wait for the X1 remote control.
A big difference to U1 is that X1 supports the Activity function where it can execute a cascading sequence of actions.
Moreover, the X1 remote will support IR & Bluetooth & Wireless connection, such as PS3\PS4\Roku Stick and more devices while U1 only supports IR & Bluetooth devices.
X1 has even further included IR Signal Boost, remote control without pointing at, Activity & Backlight Function, Stronger Database Library, Super easy to use, and Stronger Code Library.
