Hoont Solar Powered Motion Activated Ultrasonic with Flashing Strobe Light Outdoor Animal, Deer and Pest Repeller

Very satisfied with the item.

I bought this unit to place near a crape myrtle bush planted near the corner of my shed. Last winter, deer mice burrowed under it, pretty much destroying the root system. To my amazement, the bush survived but was set back substantially. The goal is to avoid a repeat. So far, seems to be working well. A few nights ago, a whitetail buck damaged a young red oak by rubbing his antlers on the trunk within 25 yards from our house. I moved the original Hoont unit to near the oak, turning it up to high frequency (with strobe lights) and high sensitivity. So far, so good, on preventing additional activity. I ordered another Hoont unit for the deer mice problem. I have to say that I am impressed with the unit...easy-to-understand instructions, and the only assembly is putting the unit on the supplied stake...two small machine screws. Be certain to charge the dry-charge batteries after installing them by hooking the unit up to a USB port on your computer for a minimum of 24 hours, so your unit is developing full power from the start of use. Afterwards, the solar power should do the job.Update: Several months after installing this product - I bought a total of two - Both have completely, utterly failed me in what they were supposed to do. The first purchased (described above) so unfazed deer mice, that they have honeycombed the area around the crape myrtle, including the area within less than a foot from the alleged "repeller". The other unit was installed very near the trunk of a newly-established red oak (diameter about 3"), after there was evidence that a whitetail buck had been browsing the lower branches, and had rubbed the trunk with his antlers. I installed the 2nd repeller within 30" of trunk, turned it up to "high frequency" (recommended for large animals), and to maximum sensitivity with both audio and strobe light warnings. Result; within a week, the buck had returned, badly rubbing the trunk - down to the white cambium layer - which will cause permanent disfigurement of the expensive tree. These repellers ABSOLUTELY DO NOT WORK, for large or small animals. Please don't waste your money!

We love this product! We recently moved to a new home on 2 acres, with about 50 squirrels, and some possum, wandering throughout the property. We did a lot of research on the damage squirrels can do to outdoor furniture cushions, etc.and were victims of squirrel damage at our prior home. Articles ranged from fox urine, to toy snakes on the ground, etc., but most of the reviews were pretty bad on their effectiveness. By dumb luck, came across this solar battery in one article and because of the cheap price we bought two of them six weeks ago. Within one day, the squirrels had moved from the areas where the units were installed, and congregated at other spots of our property. So we bought two more, and the squirrels moved again to the areas where there were no units (I think the distance one device can cover is about 30-40 feet or so, which seems accurate based on where the squirrels started moving to). We bought 2 more a week later and the squirrels are now virtually gone from our property. We will probably end up buying 1 or 2 more to cover outer perimeter of the lawn so possum don't eat some of the flowers. We are totally satisfied with this product. It's almost like a miracle given all of the articles I read, which implied that it was almost hopeless. We also like that the units are solar powered, and so far we've had no problems with any of the units that we have. One reviewer downgraded their review because the "squirrel" setting in the instructions was too low. I agree with that reviewer and it does need to be turned up a notch or two to get the squirrels to move. We also have a golden retriever, and she is not bothered at all with the setting we've used. Plus, it's easy to test at the beginning with your dog in the house to see if they react. I wish the units had a longer range than 30 feet or so, but the supplier is pretty honest about the range. And for the price, plus solar batteries, it's a great deal - in our opinion.

This seems to work pretty good. Before I was having cats dump in my area. After this, it has decreased greatly. Not 100% but def better than before.
