ASPECTEK Yard Sentinel Ultrasonic Animal Repeller with Strobe Light, 3 Mode Motion Sensor Day-Night-24Hrs, IPX4 Weather-Resistant Deterrent for Deer, Raccoons, Squirrels, AC/Battery Powered - 1 Pack

Seems to doing its job. Very few birds pooping on my boat since installing it.

Bought in February 2021, installed nearly immediately or around beginning March 2021 to deter the rabbits from front porch, (literally trails of excrement /rabbit poop) nearly everywhere. Worked for the rabbits, then a few weeks later birds started and spending days and a few weeks adjusting every setting, nothing had stopped the galore of birds from the front yard, front porch, etc. After a few more weeks, now into April I removed the Animal Repeller, because no matter what setting doesn't work on the birds, and rabbits might not be back because of the birds, who knows. I've spent more time trying to get this repellent device to work, after awhile you just have to through your hands up and know that this repellent isn't the answer because it doesn't work, PERIOD.

The device works well but the back panel is very hard to get back in. It must be perfectly aligned and takes a lot of hand strength to press back together. I think the plug to the item should be outside the box. Otherwise item works well.

The AC adapter included is UL; this matters with outdoor use, where a cheap adapter can kill you. I bought the 12v cord for it and measured current draw when connected to a car battery. My strobe model draws around 20ma at idle, and around 200ma when tripped. It has 3 potentiometers and (2) 3-position switches that can be set for many conditions; they are the key to making it suit your uses. It accepts 12vdc directly to the jack where you plug in its AC adapter. I have not yet deployed it outdoors, but I am sure it will do the job. It can detect small field mouse size up to a human. It all depends on how you set it up. It automatically resets after tripping, much like a car burglar alarm.

This device does function as advertised in the sense that it wasn't defective and it operated nearly continuously for three weeks straight until I stopped it, which surprised me. I used it in a sort of off-label manner however: I put it underneath my house set on continuous noise since there was already a raccoon living under there, and combined it with spraying coyote urine. I had hoped this would encourage the raccoon to find some other digs, but the high-pitched noise, bird-of-prey screeches, and strobe light merely turned my crawlspace into a critter discotheque. If a raccoon can live for three weeks with that constant noise, then I doubt it would actually repel one if used as suggested, as a yard deterrent. It should also be noted that I had some rodents enter the crawlspace during this period (and meet their doom as I control them via other means), so that's a double failure of this noisemaker.

Received this unit just a few days ago. After reviewing the instructions I attempted to remove the back cover panel — INSANE . They designed it to compress outside the edge of main body. It required nearly enough force to damage the unit to pry it off. That’s the easy part. After you install batteries and set the settings you have to put this back plate back on. I’m a pretty strong guy - impossible. Even if you get it reattached it will not stay. Why on earth did they not just use some screws to hold the back on…..nope….. I can’t be the only buyer who has wrestled with this. On the good side — I believe the electronics are quality and you have good adjustments. You can also connect to a 115 v power supply so batteries are not a concern (if you have that option). This occurred the second night it was installed. I have a Ring camera that can see the area where this pest device is installed. Last night both a skunk and a possum walked right up to the pest repeller and sniffed it then TOTALLY ignored it. It only made them curious. This is absolutely the truth. Worthless. Making this worse …… I just discovered a mouse chewed through the extension wire. Serious.

Works good but back cover is really difficult to put back. Almost broke a fingernail doing it. Took a bit of time to figure out how it's done but still had difficultly. So far, no wild critters coming in. Recent update: It's been 7 months after using this product. So far no wild critters coming in. Back cover difficulty can be solved if you open and close it when weather is warm making the material softer. Never do it during cold winter afternoons. Done its job to ward off skunks and deers. Leaves and new branches now growing a lot on my fruit trees since deers dont come down anymore. Seems to scare off squirrels too. Spiders can make activate it. So you gotta get rid of them if they're living in your Aspectek.

I bought this repeller to repel birds, mice and squirrels from our front porch where they love to defecate. It has worked to a modest extent, but unfortunately after 10 days or so the pests seemingly have gotten used to the repeller and are back to their old ways of using our front porch as their bathroom. Grrrr!

Ok - finally a solution. I have a boat that lives in a floating boat house in a marina on the ocean all year round in Vancouver. The otters LOVE the boat house but, as cute as they are, the smell and otter poop everywhere (and I mean everywhere) was intolerable. People I know try mothballs, ammonia, dog pee, a radio on 24x7 and even electrical wire to keep them out. None of that worked. So I figured I'd give these a go. I bought three in the fall, set them all to be on all the time and vary their tone randomly. I imagine it's a nasty, constantly changing sound. But it's high pitched, so I can barely hear it. First winter ever - no otters. Not one poop. Game changer. Hope it continues to work as well as it seems to have this far.

I installed on the undersurface of my balconey directly overlooking the rooftop of my SUV. The idea was to discourage dogs from jumping on the the car’s bonnet or peeing on the wheels. Despite the settings adjusted on the dial for cats and dogs and continuous mode selected (only ultrasound, did not turn on the volume up for sonic to avoid disturbing neighbours), cats and dogs don’t seem to acknowledge or mind its presence as they merrily do what they had been doing before. Waste of Rs 10 grands

Doesn’t work. Returning it

Dint work on dogs and cats

Works to keep my neighbors two cats off my car. I use the "continuous" mode which scans through all the frequencies in one sweep. I say continuous as the unit in this mode is on for around one minute and off for 20 seconds and then repeats. I think this more is the most effective mode. As the unit it quite bulky I stripped it down, took out the speaker and mounted it in a small soup can and attached a flexible goose neck fitting and ran a twin 16 gauge wire and soldered to the speaker. I mounted the modified unit on my 2nd story deck and pointed it down to the hood of my car. Ran the wire into the house and connected to unit. I wanted this to be discrete rather than having a unit that stands out and noticeable by neighbors.
