PERFECT! Not one scratch.

The sprays I applied GENEROUSLY and FREQUENTLY in my attic worked for a few hours to a day or so. Then I got one of your Guardians. Worked well, but every once in a while I could hear a squirrel in my attic.

I bought two more of your Guardians and installed them in my attic, so that every direction in the attic was covered. PERFECT! Not one scratch. (I set the devices at [frequencies] 5, 6, and 7.)

Thanks. And I don't think there is anything wrong at all in your suggesting that more than one device might work better than just one.
