How to use: In the following we will get the radio wave dice (Point 1 and Point 6) to explain how it works.For example,after the throwing of dice,the result we got is Ponit 1, the sensor machine will not vibrate; if the result is Point 6 after throwing, the sensor machine will vibrate. Similarly, if the throwing of dice, the result we got is Point 6, the sensor machine will not virbrate; if the result is Point 1 after throwing, the sensor machine will vibrate. A remote sensor can be used with two remote-sensing dice at the same time. The working time is about 2 hours. Advantage: 1.Simple,currency and soundless 2.no need other skills to control. 3.It is difficult to be noticed by others.
