Hi, Anand,

Yes, it has been working fine ( was in a garage ) ... no beasts nor pets around for a while !!!

but sure it gives Headaches if you're not protected yourself ...

this is very well known in Africa where Europeans use their HiFi equipment as the final amplifier !!!

But think when you will stop it ... they'll be back after a moment.

so, poisonning or gunning rats ( my .22 cal. rifle works fine for that ...) is THE solution ...

Also think those beasts come when they smell something to eat ... and have somewhere to sleep.
