Gale Force Blaster thought

I had sent two emails to the makers of the Gale Force Blaster regarding the use of two 9 volt batteries with the horn, and to my surprise no answer.  I don't like the idea of the extra heavy 12 volt battery and the space it requires, but two 9 volt batteries would be the ultimate solution.  All I can do now is wait. I am not the only person to request this same info, but they also have not heard back.  This is the first time that communication was lax with them. I hope all is well with them.
