**update**So all summer I was able to catch about 19 rats using traditional snap traps. I left this one set up and when the cold weather set in, I took my traditional traps down and stopped baiting. I honestly forgot all about this trap being out there as it had been since September that I had set it up without any action.Today, the power went out and I had to walk back behind the shed to see the pole, and noticed a great heap of dead rats laying in the bottom of the tray. I have the habit of disabling Bluetooth because it's used for tracking. Apparently when I do this it doesn't automatically reconnect, so I never got alerted. Twice I had found Rat body parts in my yard including a gut pile left by a cat and a random rat paw I don't know where from .The trap says since November it has killed 5 rats, I found 3 of them in there and they smelled pretty bad too. One was pretty fresh. I think the other two must have been scavenged.Rats are leery of new things but I guess after a while they will come figure it out. I plan to leave it set up and will make sure to manually reconnect to it once a day to check on the trap. Finding rotting rats is pretty disgusting to have to clean up, unlike a normal trap with claws I can release, I had to dump them into a bag and they were in a great state of decay.I wanted to like this product but it just hasn't worked for me. I have roof rats in my yard and they have been going right to the snap traps and completely ignoring the a24.The a24 ships with minimal information and the app is goofy. For example it tells you it hasn't synced, leading you to believe it isn't paired, but it only syncs it snaps the rat.The app let me delete my trap but wouldn't re-add it, and it took 8 days for the a24 "tech team" to fix it, but by that time I'd made the decision to return it.I know rats fear new things but the snap traps are new too and I've got 11 in them in the last 5 nights.If you're fighting norway rats, maybe this trap works better, I'm not sure if it's the bait, or what. I've even packed sunflower seeds and pb into the lure, and into the kill tunnel. If the rats weren't biting, maybe I'd forgive it but I'm getting 1-3 a night with the snap traps.Overall I give this trap 5 stars, trapping rats with normal traps requires a lot of effort and monitoring. This thing took out 5 without me even knowing, raising my kill count to 25 since September.
