I have bought dozens of different products for many hundreds of dollars (or more) from TFS. I like the shop, the people, the service... all top notch But the Waspi-brand pine squirrel zonkers (2 bags of 6 each) were sub-par. The length of the strips were inconsistent (between 3" and 6"), as was the coloration and density of the fur. I got only 6 Mr. Hanky mice out of what should have been enough material for a dozen. The good material was fine, but a lot of the material was not. I'm going to try using natural rabbit strips in place of pine squirrel.
