"Mama saw a mouse. Mama don't wanna mouse in da house. I don't wanna mess wit no mouse in da house." After looking at options, I bought this one. Followed the instructions. Two days later, there's a tail sticking out of the opening. I took the unit to the trash can out doors, open the lid and dumped it in. Cool. When it gets to the dump I hope the rest will give it a proper burial. Now, couple little things that I kept me from giving it a 5-star originally.. 1 - Really hard to separate the power unit from the trap (at least with a new trap section - still haven't forced it apart - I have a couple spares so when I have to, I will and see what breaks, if anything.). 2 - Instructions say once it's armed the light will flash, and it will buzz. Mine didn't buzz. Wasn't sure it was actually armed. (OK, it was.) 3 - Instructions say light will blink if the trap is "occupied". It does, a little flash about every 5-7 seconds. So, stop and look at it for longer than you think you should need to. Since the little feller didn't even get to the bait and the trap looked clean, after it was in the trash I closed the lid and put it back behind the commode where it was originally seen, and met it's demise, and we'll see if that was the only one.. I like it. [Update:] For 3 weeks I thought that was the lone mouse that got in the house, no more evidence of any more critters and so I decided the peanut butter dab was probably dried out and needed replacement. As I retrieved the trap from behind the commode, I spotted the tip of another tail.. apparently it had been in there a few days and was stuck - wouldn't fall or shake out. Rather than grab a stick and dig it out, I turned off the switch (I actually saw it flash once while holding it in my hand) and just smacked the trap compartment at the entrance (didn't care if it broke since I had bought a couple spares) and it popped off intact. OK, so it didn't break as I feared - nice to know it's more rugged than I thought it might be, but into the trash it went. I snapped on one of the spares, made a peanut-butter and jelly sandwich (if I'm going to dig out the peanut butter, might as well), and also put a little peanut butter in the new compartments bait well "to share". Turned it back on (again, light lit momentarily, but no buzz) and placed it back behind the commode. I'll have to keep a closer watch on it, as the "occupied light" only flashes for a very brief duration and at a longer interval between flashes than you would expect. Almost upgraded it to a 5-star, but for the marginal "Got One" indication.
