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

I was skeptical about electronic deer repellent but I was desperate. We have residential deer and our garden is totally destroyed by the end of May each year. This year the deer came in April when the garden first came up so we had to replant. With the money back guarantee I gave this device a try. The photo of our garden was taken today 6/13/2022! Not only no deer but the device keeps away rabbits and squirrels (and birds) which we have a lot of. The devices are mounted on a white stakes at each end of the gardenAbout the device, we bought the first one on May 12. It has survived numerous storms and days of rain and continues to function. It is water resistant! Second, the battery bank stores a lot charge and can continue to operate even it there is no sun for days. Third, the motion sensor is fantastic detecting objects at 30 feet and has about a 180 degree visibility . We were so impressed that we bought a second one and have each monitoring the garden with opposing views.I have one suggestion to the manufacturer. It needs an extension pole so it can be used in a garden. As the garden gets big, the device needs to extend up to look down into it. I solved this problem by zip tying each to a pole. So far I am very happy. I will write an update later in the summer after more time with it.

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!

I've had this in my yard next to my dwarf peach tree for two weeks now, and it seems to have worked really well for keeping squirrels away from my peaches. Last year, the little fellas ate every peach on my tree! So far it seems to be working great. I waited two weeks before reviewing to make sure. If anything changes, I'll provide an update. Regarding placement, I stuck it in the ground about 2.5 feet away from the tree trunk, and have it facing the tree. If anything approaches the tree from anywhere other than directly behind the device, it starts clicking and strobing. If a squirrel approaches from directly behind, it could get really close but it still has to get somewhere the sensors will pick it up before it would get to the tree. In that case, the thing is going to go off right next to him and that'll probably scare the squirrel off even better, lol. The sensor has a very wide range. I'm really impressed with the batteries. I've had a lot of bad luck with solar powered items with batteries that are charged by sunlight. You can charge the batteries in this device with a USB cable, which is nice if your yard doesn't get enough sun where you're placing it. I charged the batteries up in this the day I got it, and I have not had to plug it up since. The solar charging seems to be doing the trick. Two 18650 lithium ion batteries come with the device, so that's nice as well. I have nothing bad to say at all.
