These classic style moustraps work amazingly well but I'll be the first to admit I'm terrified of setting them. The amount of bait you use is so delicate and pivotal in whether or not the trap will work. So you load it with peanut butter or whatever, then pull the spring arm back and you have to gently lift that little metal piece and rest it in a little tiny divot in the bait piece. And you're thinking, 'There is no way, when I let go of this spring that that little divot is gonna hold this thing from snapping back.'And you let it go, and you were right, it snaps shut as you shriek like a little girl and send it flying through the air and skitteriing across the kitchen floor.Attempt #2 ends the same way, #3 you get as far as the living room before it snaps releasing yet another shriek of terror. Finally on attempt #5 you arrive at the place you first found traces of the little visitors. You gently lay it on the floor and slowly push it against the wall back behind a bookcase or desk of some sort and just as you nudge it into its final position SNAP!If you're like me, success comes on attempt #8. But, sadly, I am a wimp. Thats the long and short of it. So if you're looking for an effective mousetrap, look no further, there is no model DEADLIER than this. But if an easy to use, designed for the delicate homeowner who shrieks when startled, is what you seek, move along friend, there's nothing for you here.None of the stores in my area have these mousetraps anymore, so I was happy to see them sold through Amazon. The Victor mousetraps in our local stores are either the easy-set type or the type similar to this but with a plastic bait plate instead of the metal tab bait plate. The easy-set traps are horrible because they don't kill the mouse when they snap closed, so they suffer and struggle for minutes until they drag your trap off somewhere and finally succumb. The ones with the plastic bait plates do have enough force to kill the mouse, but have a different triggering mechanism that requires more force from the mouse to trip them. They have two settings (one on each side of the plastic trigger mechanism) but no matter which I use, I almost always find that the mouse has managed to eat all the peanut butter off the bait plate without triggering the trap.These traps with the metal bait plate, on the other hand, have never failed me. They instantly kill any mouse that tries for the bait. And they are not difficult to set. This is the tried-and-true design that has worked for generations. I guess if you work for a mousetrap company, you keep trying to build a better mouse trap. But in my opinion, there just aren't any better than these.Very unhappy. I bought this item because the size description states: 0.64 x 4.19 x 6.32 inches. But what I got is 0.25 x 1.75 x 4. If it states the true size, I will not buy them. The worst thing is I cannot return them.Can't beat the time tested spring and wire metal mouse trap design. I tried a couple different brands of plastic ones and I had several baits eaten without triggering, and several triggers without catches. I bought these online because you can't find them in the store any more, but I remember having success with this style 20 years ago. I set them and within two days I had no more mouse problem, catching several in the same trap where they were all hanging out. Now I have them tidily stored away in a safe place in case Victor stops making them and I need to use them again.The reason you can't find them I think is because people tend to trap their fingers in them just as easily as a mouse gets stuck and retailers don't want to be sued. Just be careful before you set them, think it through, and you'll be fine. Even if you do trap your fingers, it hurts like hell, but it's not enough force for any kind of serious injury.Every year, when it gets really cold, we're bound to get a mouse in the house. We've tried every type of mouse catching system available, but these old-fashioned traps work the best. We tried the newer kind with the plastic piece on the top that are easier to set, but they are not sensitive enough to catch light-weight mice--we just ended up feeding those little buggers because the trap would never trip. We bought sticky paper, which worked, but it is just too horrible and inhumane. We bought the expensive, humane kind that is supposed to trap mice without killing them. That has NEVER NEVER WORKED!!! Not one mouse, ever. My husband refuses to use poison because he's afraid the dead mice will stink up the house. So, I ordered these old time wood and metal traps which are almost impossible to find in our local stores--they've all switched to the plastic ones, which rarely work. We killed our resident mouse the first day after receiving these in the mail--no more mice. They are very, very tricky to set, but worth the effort if you want something that works.Good valueThat can be good or bad. This one will not snap by itself in the wind but is harder to trip and sometimes they eat the bail. For an inside trap I would go with the ones that have a plastic yellow piece of fake cheese for the trip part.It came without damage and I was able to use it for my physics project. It came with two.Esto es para ratones y no para ratas. Usé mantequilla de maní para cebar la trampa. El roedor tomó la mantequilla de maní sin romper la trampa.
