We live out in the country, and thought this would be a great way to deal with the mice problem -- and keep our doggies safe from the bait.However, as you can see in the photos presented with this product, the baits are attached only on the bottom -- not on the top.What this means is an enterprising mouse or rat can actually REMOVE the entire bait, with the bar, and take it out of the box.This is what happened in our house. We were horrified to find an entire block of bait, with bar, sitting at the bottom of a closet.When using the old paper bait boxes, you know to keep them under counters and away from pets. And the worse you're going to have to deal with is a small pile of pellets stored away before the mouse dies. With this? You may end up like we did, WITH AN ENTIRE BLOCK OF BAIT OUT WHERE YOUR PETS CAN GET TO IT.So I rate this product as a great idea, badly executed.
