Review: Works Well - I have used one of these for years. it works very well in our kitchen, in conjunction with good housekeeping measures. A hungry rodent will put up with the discomfort if it can smell food waste. if it can't smell food it will stay well away. Empty waste bins every day. it says on the packaging to allow up to 28 days for a full deterrent effect to occur. This device definitely gets my vote. Incidentally, the delivery was poor. The driver knocked briefly on our front door. He did not wait for us to answer. He left the package on the ground adjacent to the front door. By the time we opened the door he had gone. This was less than 2 minutes from knocking. He certainly did NOT hand the package to the customer as is stated on the final delivery note.
Review: Seems to work - It is always hard to tell how effective these things are but my loft has been mouse-free since putting a few of them up there. The incessant beeping when the battery needs replacing is a bit bothersome for something that is typically placed in an inaccessible area and can't immediately be tended to. Batteries are lasting around 3 to 4 months for me.

### ⭐⭐⭐⭐⭐ These work I bought one for my attic because I heard mice
*by N***D on 29 August 2023*

It did not work at least at first so I bought another one and place both ends of my attic we have had no mice in 5 months in house or attic. I also sealed up all holes I found near kitchen pipes with wire mesh I recommend this. Recharge the battery's every 2 months
