Cleanrth TSAR520 Advanced Ultrasonic Animal Repeller w/Triple Scan Technology

Well, this is my second purchase. I installed this one in the back of my house because I have deer who think that they live here. I contracted Lyme Disease because of them and I'm still taking antibiotics trying to get over the side effects.
The day that I installed this one, I returned home to find two deer, one was trying to stay away from the repeller and the other one was lying in the grass where a tree was blocking the repeller. God forgive me, but I acted like I was going to run that deer over and he bolted. I repositioned the repeller and the other deer jumped the fence and left.
Happy to say, THEY HAVE NOT RETURNED!!!
Thank you Cleanrth for a product that does what it's supposed to.

I purchased four of them in the last three years. I use two of them to keep geese and ducks off my lawn. They work 90% of the time. I have both set on the highest range. The lower range wasn’t as affective. I wish they made better quality off/on switches. The switches failed on both units after being out in the elements a few months. I’ve had to spray both of them with electrical contact cleaner to make them work again.

I had been trying for two years to find a way to stop cats from living under my front porch. There's a very large bush in front of where they get in, that I can't afford to get cut down right now. The day this arrived, the cats were laying on my steps which made me very angry. I set this up in about 15 minutes, found the perfect spot to place it and went to the store. When I returned, the cats were on the side of the house! I thought" that's odd". I went in through the back door and noticed a deer laying near my sun porch.
I was looking out the back window when the deer left the yard and it jumped the fence and went through my neighbors yard to avoid going past the Repeller. Now I know I need one for the back yard also. That same night I kept watch out the front door and the kitten was walking around the Repeller and it was bright red; the kitten left first. The mother cat tried to return a day later but left and hasn't returned. I was passing by my neighbor a few days ago and he literally hollered "thank you, Sharon! so many times, I thought he had lost his mind. I finally dawned on me that all the strays were gone and he was just happy and thankful. This product does exactly what it claims to do and I decided to purchase another one for my back yard. Buy this and you won't be disappointed! I do have one suggestion. You should us the cord option that is supplied because I think that batteries will wear down a lot faster if you have a lot of critters :)

I purchased this particularly to get rid of the squirrels that kept knocking over my bird feeders and eating the seeds. In the short period of time (It has not yet been a month yet). I have noticed a reduction in squirrels. So far so good. I was pleasantly surprised that the repeller was made of sturdy plastic. Included was very descriptive directions and information. You can't go wrong trying it out especially with the support of the company. My only complaint I wish it was more affordable.

Overall very easy to use and set up comes with a super long extension.
