Product description New model optimization: 1: After turning on, it will randomly sound every 2-5 minutes (the time interval has been optimized, too long intervals will easily make end customers lose patience). 2: After turning on, it will no longer automatically power off and will continue to sound (if the power is not removed, the end customer will think it is broken). 3: The chip has been upgraded, and the sound is more realistic than the old model. 4: The sound can be selected, which is convenient for end customers, for example, if they only want to use crickets to prank family, friends or colleagues, or only want to use one noise, it is more functional.
