I bought this several weeks ago. It works as advertised. I had rats in my attic in an area where I didn't have access above my bed. I removed a ceiling speaker and put the Zapper through the hole and attached the optional Rat Tail. I used dry cat food for bait since they had been eating that. The first night I put it up I came up empty. The second night I heard a loud buzzing sound and the Rat Tail lit up. Next morning I pulled it out with a dead rat and dumped it into a trash bag. Next night the same thing except the Tail didn't light up. Damn rats chewed the cord on the Rat Tail. Next day I got 2 more. Anyway I got a total of 6 in 5 days. I now am rat free after sealing up all the holes where they can get in. The customer service is first rate. I can't recommend this enough. My only regret is you have to empty it after each kill so if it is in a hard to reach place you have to pull it out and reset it. It's expensive compared to a spring trap but there is no gore or danger of smashing your fingers. It was worth every penny to sleep in peace again.

I am glad I found the Rat Zapper as my husband wanted to use those cruel glue traps to catch the mice in our house. I was dead set against it so I researched the Zapper. The Rat Zapper is perfect. It is the most humane way to rid your house of mice besides the havaheart traps (which are less effective towards the population of rodents). The best part about the Zapper is you don't even have to look at the carcass. Just get a bag and dump the end of the Zapper into it.
At first it was hard to catch any mice as you need to find out where they are coming in from or congregate. We needed to find areas that our animals would not interfere with the trap as well. It took us placing it in several spots until it became "very effective". Once we placed it in the percise location, it was successful many times. I do suggest using crackers with a tiny bit of peanut butter on it to lure the mice into the traps as the bait that came with the Zapper did not appeal to them. It won't be long between the Zapper and our cats before our house will be pest free. Thank you Rat Zapper.

At first we thought the Rat Zapper wasn't working. Then after five days we zapped a rat for twelve nights in a row. We would not be without one now.

I'm returning this item. It does not work - haven't caught a mouse yet even though I know they are around because I can see their droppings. May as well use the regular mouse traps - at least they catch the mice!

Best device on the market for killing rats...I love going to my crawl and seeing the eyes on the rat tail blinking...I have gotten more with this device than any traditional traps...If you through away your traditional traps this device will eventually pay for itself...
