Someone here has written the well does it with Nutella, which I agree with 100%. Thanks a lot for this.
Now for my reviews.
1. The cases correspond visually and structurally not to fall in the pictures. DerBügel clamp around the bait does not exist. But since I take Nutella, no problem.
2. In a case of the wire is too long, so I do not stretch the case so can not use. Well, I have indeed placed only 5 cases, in spite of everything have 10 paid where only work 9.
3. I do not know if that's only in these snap trap or so in general, I find the performance too weak. The traps would need much more power. I had also caught little mouse with it and at the mentioned (which is random !!) was hit his neck. 2 of 7 mice were killed instantly. The rest would be agonizing choking if I had not freed earlier.
These traps are incredibly cruel and will now dispose.
Live traps are expensive but better alternative.
