This thing is no where near 129 disables 129 disables is what an ambulance puts out this thing is 70 disables at best . I am not saying it functions poorly the sencors work great and the solar charger is super but it is not loud as you claimed it to be i would be happy if you sent another to mabe compare them in sound if the new one is louder ill pay for the one you sent and keep the old.one too .eather way I won't send the old one back
