When I use the SG-1, the dog typically leaves the room to go sleep under the computer desk nearly at the other end of the house.
The cats, who you would think would be more sensitive to noise, couldn't care less.
When I use the Hermes 3000, the dog will remain in the next room, but still does a lot of sighing nervously.
The cats continue with their inability to care less.
Conclusion: that my cats are broken, and my dog has no taste.
Oh, and that the SG-1 thunders while the 3000 just sounds, as Olivander put it, rather like scissors. Lots of scissors. Be afraid; be very afraid.
