Reviews about GRAD A-500
Compact, quiet
Expensive
We have a 2-storey house, we live on the first floor, the second is still closed. We are already living our second winter. Everything was fine until this winter. Mice have entered the house, running around the 2nd floor, in the walls (in the gaps between the drywall and the timber). There is a cat at home, they are not afraid at all. We bought the A-500 hail. 3 weeks have passed, it has been working for days. No mice are heard or seen. A child, a dog, and a cat live at home, I did not notice any influence. Everybody sleeps well

I turned on the device and put it in the attic, where a mouse walked around at night! A week later, the footfall of the night visitor disappeared, apparently the sound made by the device did not like her! Of course, I myself did not believe in this miracle of technology, but the fact remains! Try it!
Works as advertised. Not expensive. Virtually silent.
If there are any disadvantages, then compared to rodents, they are so small that it is not worth writing about them.
I heard about the device, rummaged in the net, read reviews, those. har-ki, stopped at the Grad.
In the first 2-3 days, the animals were still in charge, then it became invisible and inaudible. With the beginning of the autumn rains, they came again - the minks began to flood. But they did not stay long, also 2-3 days.
I became calm, otherwise the mice pissed me off. Well, I'm afraid of them! However, like most girls))) I am quite confident in the device. I live in a private house, I don't keep any cattle, not even a cat or a dog. But the neighbors have chickens, pigs, rabbits, turkeys, pigeons ... It is clear that there is plenty of food for rodents. But for some reason they also come to me (maybe the area there is small).
It happens that I turn off the device for the day or night. Still, you can hear him and blinking in the dark is not always pleasant to watch. The ears, of course, do not block, as they write here, but there is a slight crackling. It also depends on the ear, maybe someone has it musical)))
In the summer I'll see what happens to the moles.
You should ask the neighbors about the rodents, or maybe it's time to take a fee from them)))
I do not consider it an expensive pleasure, because these creatures will spoil more than you pay for the device, and cleaning after them is not a pleasant pleasure.
