I'm thinking about buying one of these

They get very mixed reviews.
The basic mechanism seems sound, they're just really flimsy, and sometimes the rats somehow chew through the top.
Since I had 2, now 1 bird in an indoor bathroom, when I open the door there is a flurry of mice and rats.
I am careful about only giving the birds "enough food for today", but the rodents are still coming.
Not surprising, since our house is on the edge of a very dry forest, between that forest and a creek.
I have been trying to use a Cat as a deterrent but he seems to have given up on eating them, though he does make a good scarecrow. On nights when he is indoors, the rats are much more quiet.
BUT they messed up some papers in my office. Therefore they have crossed a Rubicon.
One thing I did was to drill holes about 5 feet off the ground in the wall board, between the wood studs, and drop in Mothballs.
That works very good, although it only causes them to vacate those wall sections.
