Bought this to control my Matricom GBox Q2. It works great when its working at full potential. The major drawback to this is the range. Seems the optimal range is about 6 or so feet. Outside of that range you will have a lot of issues with the remote connecting and disconnecting to the dongle. Other than that its a great size and function combination. Internal battery is charged with the provided usb cable. Keys are backlite for seeing in dim to dark times. Makes typing a lot better than having to use an onscreen keyboard, which is the main reason I bought this.
It uses a USB dongle to communicate with the device you are trying to control so if your device doesn't have a USB slot you will not be able to use this product with it
