Review: Bird problem solved. Cross-hatched angles are more effective for extremely large coverage areas. - We had been unable to use the patio surrounding our home because of bird droppings which we only discovered shortly after moving in. The prior owners must have washed down the decking every time they were going to show the house. Yuckola. We still take our shoes off after coming in the house just in case. We were feeling a bit desperate; the gorgeous trees add a lot of privacy which we are loathe to give up. This machine seems to have worked on the doves as well as the large black birds (crows?) we had been getting. We have this mounted to the eaves of our house which puts the machine at about level with the lower third of the canopy of our very large fig trees. Per the owner reply to our question that positioning should work as the machine covers a 70 degree arc up and down (presumably a 140 degree arc total). We turned the dial to the right just short of where birds/skunks transitions into cats/dogs and it does seem to be working. It's been 72 hours thus far and no more bird droppings. We had been really frustrated and skeptical after we tried the reflective strips and other visual cues to scare birds away because they only seemed to work for a week or two. We've had this up for 72 hours so far and as of this morning, we are giving it 5 stars for being incredibly effective. Will update in a few weeks with additional results. ================= UPDATE 1: First week of use: This machine continues to be effective and humane; and it has made us much happier with this home we recently purchased last fall. We still see birds flit by and maybe even come down to grab twigs for nest building but there are NO MORE huge piles of messy droppings littering the deck every morning. We still get hummingbirds for the flowers, but again, no nesting. All we see now is leaves and twigs which are easy to sweep off and much much much cleaner. This machine is perfect for what we need. We've kept it on the same continuous and ultrasonic only setting just short of where birds/skunks transitions into cats/dogs and the audible noise volume is turned down to zero. We thought we would have to work our way down the spectrum every 3 or 4 days until we found the right setting for the local birds here, but it looks like we got incredibly lucky and hit the correct frequency on the first try. Will update periodically after several weeks and then several months of use with progress updates. If all goes well, we will be recommending this to friends who are getting bird strikes on their windows. Bottom line: Continues to be a 5-star solution. Confidently recommended for overnight bird roosting and nesting problems. ================= UPDATE 2: First month of use: Well, we've had some ups and downs. We decided to try changing the frequency to see if we could get an even broader effect so that pigeons would not even land anymore to get twigs as we were getting the occasional dropping on the deck just from that and it turned into a disaster. After just 24 hours of the changed frequency we started having problems again. Then we changed the frequency back, but it turns out that we had left it unplugged during the change back to the original and forgot to plug it back in. Our deck was a mess. The whole thing had to be hosed down again. And we washed off all our furniture, etc. That was horrible. After we plugged it back in, the droppings seemed to reduce by a lot - about 80% over night; and then completely stopped after about 48 hours. We cleaned everything yet one more time and fingers crossed we've been good ever since. And curiously enough, even the occasional landings seemed to have disappeared. Maybe its because when we made sure the frequency was set for the third time, we must have tweaked it just enough to be perfect. So that was overall a huge win. Now however, we have some new smaller bird that seems to be flitting around and nesting at the margins of our deck - or at least that's what we think from the teeny tiny pile of bird droppings. Still gross but a better problem as the sheer square footage involved is smaller and in an out of the way corner of the decking we can clean more easily. So after some discussion, we've decided to leave the first unit alone as it's working great. We had our first rainstorm and the box is mounted on the eaves where it still gets direct rain and run off from the roof as well and it's still working great. To figure out this other smaller problem, we're going to purchase a second unit and set it at a different frequency to see if that works. Hopefully the new ultrasonic frequency won't cancel out the old one. Will keep this posting updated. Bottom line: Continues to be a 5-star solution. Confidently recommended for overnight bird roosting and nesting problems for doves and large blackbirds and some other large bird of some kind. Purchasing a second unit to experiment with another frequency for smaller birds. ================= UPDATE 3: Full 90 days of use: Make sure all angles are covered! After some accidental re-alignment we figured out that the problem we had been having with smaller birds was due to occlusion and not the frequency; so all of the birds species - large and small - are driven away by the same frequency (continuous and ultrasonic only setting just short of where birds/skunks transitions into cats/dogs and the audible noise volume is turned down to zero). These units work on line of sight so obstructions near the unit can block the coverage area farther out and birds find these safe zones and roost there. We used the second unit then to generate a cross hatch coverage perpendicular to the first unit at the same frequency. The area we are trying to keep clear is about 50 ft deep x 80 ft wide, surrounded by trees about 30 - 40 feet tall. Both units are mounted about 10 feet off of the ground pointing straight out. One unit is mounted at the center of the 80ft wide section. The other is mounted at about 10 feet in from the corner along the 50ft deep section. For us the results were immediate. The resulting invisible cross-hatch of ultrasonic sound is incredibly effective; overnight the deck was completely clear for the first time ever. We are extremely happy to have a droppings-free deck to enjoy year round. This product has made our yard usable.
Review: Totally worthless scam. Don't waste your money. - I don't understand how can this device have so many positive reviews when it is clearly a scam. I can only think they are also fake reviews. I always give products 5 or 4 stars minimum (you can check my ratings), when I have nothing good to say about a product, I prefer not to say anything. But this product is just a plain scam, so I had to say something to avoid other buyers get scamed. I bought 2 units for my small backyard. I carefully read the instructions, so I did everything as per the manufacturers instructions. It suposedly has one (undetectable by humans) ultrasonic sound plus one audible sound. You can set the volume for the audible sound only, the volume for the ultrasonic sound is fixed. It has a motion sensor that is supposed to detect the pest you want to repel and it starts the audible sound, while the ultrasonic sound is supposed to be always on. I wanted to scare pigeons that drink water from my pool. I placed the device at 3 feet from my small pool, and set the volume for the audible sound to 3/4 of the maximum (it says it reaches more than 90 meters at it loudest setting, and it certainly is very loud). Note the volume setting is just for the optional audible sound (that is suposed to increase eficacy of the product), the ultrasonic sound is supposed to be always on, and at a fixed volume. I had it just one day (so no point in saying that pigeons got used to the sound and so they are no longer scared by it), and pigeons just walk happily a couple feet from the device without any discomfort at all. A couple pigeons even fell asleep at about 15 feet away from the device while it was making the loud audible sound. The motion detector also fails in detecting any pigeon, but it starts a loud and very uncomfortable sound for humans everytime a person walks by. The sound gets heard all over my 500 sq mt house and it even annoys the neighbours, but pigeons are not disturbed at all by it.

## Features

- ADVANCED DUAL TECHNOLOGY: Uses powerful ultrasonic frequencies and an optional sonic alarm to create an "unfriendly zone." The built-in Night Time Scanner and Infrared Motion Sensor detect movement up to 5500 sq. ft., triggering the device only when pests are present.
- LARGE ANIMAL DETERRENT: Engineered to repel outdoor intruders like Deer, Raccoons, Skunks, Rabbits, Foxes, and Geese. Note: This high-intensity outdoor unit is designed for larger yard pests and is not intended for indoor rat or mouse control.
- 3-MODE SMART PROTECTION: Switch easily between Motion Sensor, Constant, or Continuous Sweep modes to match your pest pressure. The infrared sensor detects movement, activating the 24-hour Day/Night scanner exactly when needed for maximum coverage.
- IPX4 WEATHER-RESISTANT AND DUAL POWER: Built for durability in temperatures from 14°F to 122°F. Features an IPX4-rated housing designed to withstand splashes and light rain; for best results and longevity, mount under a slight overhang or avoid direct vertical downpours. Includes a 10mtr AC extension cord for constant power, or runs on 4 C batteries (not included).
- PRO-TIPS AND INSTALLATION GUIDE: Prevent animal habituation by rotating frequency settings every 2-3 weeks. For best results, install one unit every 5000 sq. ft. with a clear line-of-sight, as ultrasonic waves cannot penetrate solid objects like fences or dense walls.

### ⭐⭐⭐⭐ Works pretty well (at least at first) on field mice
*by L***A on June 5, 2016*

I have some pesky mice who had taken to hiding behind the A/C unit and ended up chewing through some cabling requiring repair twice. We got the cables sealed up again and screened off everything we could but they still congregate there and leave their droppings. I've cleaned there multiple times and tried some easy repellent like peppermint oil. They definitely don't seem to like the oil but it wears off quickly and is hard to disperse everywhere. I have tomatoes and other veggies growing in containers and really got annoyed when I saw some chewed leaves and droppings on my favorite tomato plants. Gave this a shot and have to say it seems to be helping. It definitely got them away from my plants so I moved it to the true test behind the A/C. It worked (I check for the amount of droppings)! The "hawk" sound it makes I'm sure is/was effective given we have one that I've seen swoop in a few times and once with a mouse in it's talons. I have noticed now after a couple of weeks though that droppings are there again. I am hoping it is just because the batteries are dying and not because they've figured out it is harmless. I am going to attach an extension and keep it plugged in and turn it up a little bit and hope for the best. I love all critters and these little guys are kind of cute but I really don't want them near or in the house or munching on my garden. I just want to deter them not hurt them. This seems a good option. I docked a star because as others have noted that the back cover is really difficult to get off and on but you have to take it off to get to the controls. If the intent was to keep it water tight I doubt it really was and there really has to be a better design.
