Yea, nice and quite too! I don't have to hear "chirp chirp"!!! I remember when I would goto bed, and there would be some crickets that did get out...oh man! I used to look for them, then they would shut up...then you could never find them!
Also a GREAT thing to feed your roaches is that Roach Buffet on blaberus.com, I just got 15 pounds of it! I USED to make my own, a little bit of cereal, oats, fish flakes, dog food, calcium and the herpitive...I thought that was killer, just got the Roach Buffet today, and my oh' my...they went and ate a crap load...! I was shocked!
