I've used the chocker style versus the snap style traps. Both work well on mice. Chocker styles tend to be 100%. Snap styles can be 90% effective and requires you to put down the mouse in the other 10% of cases when it catches a limb only and not the head for an instant kill.
This is a snap style trap but instead of a metal bar that comes down, the entire lid snaps down on the mouse.
The bait cup is separated from the trap at the bottom and reinserted with a twist. It does this because it uses the entire lid to kill the mouse so its hard to keep the lid open while baiting the cup. The problem with the two piece system is that the cup, like every bait cup gets dirty. There will be rodent blood on it and I personally don't want to try to twist the dirty cup off to put more peanut butter on it - I just want to smear it on the existing cup. So you would have to carefully lift the lid and put some more peanut butter before setting the trap. A traditional snap trap doesn't have this issue because the bait cup is fully exposed when the snap is down.
The good thing about this style is that when the trap is activated, the bait stays inside the trap and may be inaccessible to squirrels and rats early in the season. The traditional metal bars leave the bait 100% exposed and taken. Some animals become smart enough to set the trap off and take the bait.
On the flip side, and from experience, over time, the rats tend to chew through the plastic to take the bait. So these traps don't really have a super long life compared to the traditional metal bar snap traps where they can easily access the cup and leave the trap whole.
I know this from using chocker styled traps and the rats just chewed through the plastic to get to the peanut butter. Creating a hole in the actual trap and rendering it somewhat useless.
So if you just have a mouse problem, this will work. Easy to dump the mouse into the trash, then reset the trap for the next one. If you have both a mouse and a rat problem (which we do), this usually works at the beginning until a rat figures out he can get to the bait by chewing a hole through it once he sets off the trap.
