Question: What is the output of the power adapter that comes with it?
Document: I have installed it in the attic, cranked full blast for 4 days and then switched it to medium power. It really works. No more chipmunks rolling nuts in the attic.
The only thing it repels are my neighbors. The power company came thinking there was a short or a live wire in the backyard. I finally disconnected it. An extra star since it did work outside through the whole winter in Chicago in the sub-zero temperature.
I have used this electronic pest repeller in my hunting camp (in the middle of the woods) and in my barn. The devices are on timers and set on full power for rodents. I use multiple devices in the barn due to it's size and one in each room at the hunting camp. I disconnect them when I'm there. Prior to using these electronic repellers I consistantly had problems with rodents (mice and rats)getting in the buildings, especially during the winter.
This repeller worked for us. You can't leave it on because the creatures get used to it.In Five minutes the squirrels leave the roof. the mice leave the house, the flying squirrels left the attic. I'm so glad there's something that leaves no poisons, dead animals, doesn't seem to bother our pet birds.etc. Yes, it would be even better if someone comes up with something humans can't hear: have they?
not exactly what i expected and it`s very noisy. would not recommend anyone buying this. too costly and not a good deal
i was very happy with all  i do wish it would have direction on hoe to get music of my likihg downloaded  im not a teck person
great product. so far so good.......  A little noisy but we have in the attic........I recommend this product, it works!
died (i.e. in a trap, rather than in a wall somewhere).
You should only buy this if you have a serious mouse/rodent problem. Our office building has a severe mice infestation, and nothing else worked. We used several of those un-audible devices but they made no difference. Only this unit set on high keeps the mice away. The sound is VERY audible at this setting. (Even for our neighboring office). We only put it on when we leave the office for the day.
You could definitely hear it when you walked under the opening and while sitting in the surrounding rooms but I was very happy to find that all of the animals ignored the sound. I am happy to say that was the end of the squirrels! We left it on for several weeks then turned off so the wouldnt get too used to it. They did come back a month or so later but I just turned it back on and out they ran. Well worth the money for this product and it does work.
Answer: no
