I had read literally HUNDREDS of reviews for this product, both good and bad, but leaned more towards the positive when I decided to place my order. We had been finding “evidence” of these little critters for months on our counter, black stove and in kitchen drawers, but nowhere else. We had two cats that usually took care of the problem for us, but one of them moved out this summer with his owner. That’s when we found out that the tuxedo kitty was WORTHLESS and were about ready to borrow the one that had moved out for a few months to show Mr. Tuxedo what a “real” cat is supposed to do!!Enter the Victor M250S Indoor Electronic Humane Mouse Trap.When I was scrubbing the stove one day, awaiting our new kitty replacement, I noticed there was an area that was especially dirty below the digital dials for the temp & time, etc. I thought that was just a regular vent that heat comes out of when in use, but apparently, it’s a super-highway for our vermin friends to gain access to our counter. The few times we didn’t get a chance to do dishes before bedtime, we would awaken to used frying pans on the stove that one could only describe as a community port a potty for these ba&%#rds that had invaded our home.When our Victor trap arrived on 12/28/2022, I did exactly as instructed. Put in fresh batteries, put a tiny piece of peanut butter in the space provided being extra careful not to get any on the electric part using rubber gloves so as not to transfer my scent, then placed it on the counter next to the stove.Day #1 nothing but mouse poop on the spoon rest on the counter.Day #2. Made sure nothing edible was on the counter or stove. Nothing.Day #3, same thing.Day #4 God as my witness, that night my roomie fried up a few pieces of ham in a pan and sat down to eat. I walked past the kitchen to the living room, sat down and saw something out of the corner of my eye in the kitchen. All the lights were still on which made it very easy for me to see that one of our furry enemies was on the stove heading towards that frying pan!! He got up on the ledge of it and it must have still been too hot for his little feet, so he backed off and scurried behind the stovetop but not so much that I wasn’t able to see his paws and nose twitching, just waiting for the pan to cool down. I situated myself so I could see straight into the kitchen to view his little antics and sure enough, about 5 minutes later, there he was….IN THE DAMN FRYING PAN. I got of my chair quickly, walked towards the kitchen and stomped on the floor, thinking that would scare him off, but all he did was jump out the pan, turn around on the stove, and had a stare-down with me!!!OK, GAME ON!!!I took the frying pan, put it in the sink with soap and hot water and proceeded to set him up for his demise. Keep in mind that this whole time, the Victor trap was only inches away from the stove this whole time with peanut butter in it. Apparently OUR mouse had a more discerning pallet and preferred meat protein. I donned rubber gloves and carefully cleaned out the peanut butter and got out my jar of saved bacon grease. He was gonna LOVE this, I just knew it. I smeared a tiny dab of grease in the designated spot and set the trap next to the stove. I then took about a teaspoon of grease in another frying pan, heated it up to melt, then placed the pan on the counter right next to the trap. I knew the smell would be irresistible to him. I swear he was actually watching me as I was using the stove!! It took him maybe 2 minutes once I backed away, to get on the counter. He meandered to the frying pan immediately. It must have still been warm, because he backed off and proceeded to clean his little paws while perched ON TOP OF THE TRAP that was right next to the frying pan!! Bath time completed, he hopped into the frying pan and proceeded to lick off what little grease he could, then scurried back behind the stove.Day #5, nothing.Day #6, nothing.Day #7, the roomie and I both got a touch of the flu and barely went into the kitchen for anything.Day #9, I was more on the mend and went into the kitchen to make a cup of coffee. No green light and I couldn’t even remember if I had re-set the trap because I was so disappointed in the product. Not sure if it’s really the fault of the product or not. OUR mouse was just too smart and apparently a picky eater. Because we had the flu, there wasn’t anything on or near the counter for any “visitors” to eat. I took a look at the trap and no light was flashing and my brief look inside didn’t appear to have one in it so I set it back down on the counter. I was going to return the trap later that day but since I was there, I would slide the on/off switch to make sure it was set. When I did, it smelled funny; kind of an electrical smell and I wondered if, since I hadn’t been feeling well, that I hadn’t been able to smell that when we first got it and that that was what was keeping the critters away from it. I went back to my day and didn’t think about it for a few hours until I mentioned it to my roommate. She asked if I was certain it hadn’t caught something. I double checked, and sure enough, it was full! The bacon grease worked!!An hour later, the roomie was making a piece of toast. She had left a stick of butter on the counter the night before to thaw and this is what she found. Pic attached. It looks they were eating it like a cob of corn. This had never happened before! I don’t know if the mouse the trap caught had eaten the butter before getting on the trap or if he has friends that like meat protein too, but we were totally grossed out!I’ll be re-setting the trap with butter this time to see if any friends are tempted.Be patient and try different kinds of bait. It works!!*** UPDATE ***That next night, the trap caught another big fat one and we haven't seen any new poop on the counter since. I find it hard to believe that we only had 2 total in the whole house, but time will tell. I'm going to put some fresh batteries and fresh butter and keep it on the counter until we are convinced we have them all. Being that it's small enough to not be in our way for cooking, etc., there's no reason not to keep it up and set. VERY happy with our results!!
