Bird-X Balcony Gard, Ultrasonic Bird Preventer, Outdoor Bird Decoy with Motion-Sensor, Easy to Install, Covers up to 900 sq. ft., 15 to 25 kHz Frequency, 6.75" x 5.5" x 3.5"

Got tired of birds hanging out under the awning over my deck so I ordered one. Glad I didn't waste my money on 2 of them. The birds no longer gather in my tree, but have found life under my awning more enticing. I now have alot more birds than before. This so called balcony Guard" does NOT work & is a complete waste of money. Svae your money & put up a bit of screening. Works & is alot cheaper.

We have had this on our porch for nearly a year. We have it plugged into power so we don’t have to change batteries. It has helped deter the kestrel we had wanting to roost on the porch. We can adjust the frequency so it is not heard by people and that seems to be the tone that works for the kestrel. We purchased a 2nd one for the back yard as well.

I purchased one of these last August. I have it placed on my covered front porch in the back corner, at a 45 degree angle in order to effect the entire front porch, which is 7ft x 8ft. and it is no longer effective. I wrote to the manufacturer explaining that I was unhappy with having to replace the unit after only 8 months of use. The following is their response: "So if you wanted me to replace the one bought in August, I wouldn’t be able to since our warranty are for 6 months. Also remember that the Balcony Gard is a very directional unit meaning that you would have to place it directly where the problem is. I suggest trying to place the Balcony Gard in the corner facing outward and elevating it a bit that way it covers 3 feet below and 3 feet above." The distance between where I have the unit placed and the area which is now covered with bird poop is about 6 1/2 ft, at the same level. I can't recommend this product Since, when I first bought this item several years ago, it worked very well for several years, I decided to give it one more try. I received a new unit last week. I placed it in the corner of the porch, settings on high, aimed directly at the area which the birds seem to like, and turned it on. By the next day (and almost every day since), there is new bird poop on my porch. I don't know how their technology was changed, but as far as I'm concerned, this was a waste of money.

Pleasantly surprised to find this product works very well. We had mourning doves that had already nested twice on our balcony, leaving a big mess. We installed this using the AC outlet so that we could make the device work continuously. I turned the sound up as high as it would go. These birds were very drawn to our balcony so we thought they might be hard to deter. At first they came on the balcony but stayed all the way against the far wall indicating they did not like the sound. They only stayed a minute and left right away. They tried this twice in one day and they have not returned. We installed it about four days ago. One thing I would caution you about - make sure nothing is anywhere near or in front of the device to block the sound. At first I had a plant right next to it, and then I moved it about 6-8 inches away making sure it was not out in front of it and it made a difference in how the birds reacted to it. We can't hear the sound so that's not a concern.

This review is from my personal experience having this product for only a few days. I bought the Bird-X Balcony Gard hoping to keep pigeons and blackbirds off my back patio. Setup was easy, and I appreciate the motion-sensor activation. It does seem to deter some birds, but not all—particularly the more stubborn ones. The ultrasonic frequency is silent to humans, which is great, but its effectiveness seems hit-or-miss depending on the species. I noticed a slight reduction in bird activity, but they still linger occasionally. For the price, I expected a bit more consistency. It’s a decent option if you want some kind of deterrent, but don’t expect a miracle solution. It is essential though to prop it at least 3 feet from the ground. Initially I only put it about 1 foot and it didn't work at all.

I use this as one method to keep the birds away as they were destroying my paint on my cars which had cost me about $1000 in repairs. With two owls, holographic tape, sticky bird caulk it did the job, This was the last thing I tried since all the others only got me 80% of the way. Some birds might sit on my owl head mocking me, other sit above the holographic tape. But those were only minor players. I wanted to stop birds from my neighbors house that nest in spaces in the house that should be sealed. The birds would fly in and out over my cars and the neighbor, to say the least is less than helpful. This device stopped maybe 99% of the fly overs. It is unpleasant for them to hang out near my cars now. Much less birds. To the bird, the shinny cars look like lakes and a good spot to splat bird droppings. Inside (in the back under the plastic push on cover) is a frequency control and range control, and a jack for the 9V adapter and place for 4 C batteries and power switch (battery or power jack). When it is triggered, a red led lights in the sensor and it makes as short audible twerp (plus the actual sound that continues) . I like it but there are some down sides. First off the frequency control adjust differently if you use the adapter (starts I think at the 15000 hz) than the batteries (6V) which I believe is somewhere around 14000 hz. Though it may actually be between 17.5-18.5.This is because there is no voltage regulation internally. As the batteries wear out the frequency drops from where you set it, until it finally goes insane making crazy noises. I also notice it was temperature sensitive as to the frequency (in the cold it drops) and goes crazy. Let me tell you why this important besides being annoying. There is a device named the Mosquito which is used at train stations and parking lots that is teenagers hear that is annoying and they do not hang around. This is a costly item. This device with the batteries, send out the 14000 hz signal (or 17.5-18.5) and above or lower with the batteries . So it can be used for the same purpose on the cheap and I can tell you it works. It can be adjusted that teenagers, some women, and other ages hear it. I had to have my neighbor's kid stand there so I could adjust it so he could not hear it as he could hear it 25 ft away through an open window. Those frequencies do not go through walls - only openings. As the batteries died, it would swing the frequency down back into the torture range! A food delivery person once came and he was holding his ears in pain (he was 3 ft away) and was saying what is that, what is that , it hurts, while I heard nothing. He was running away as I gave him his tip. So point is human beings can hear a tortuous sound if it is set to too low a frequency. But maybe that might be want you want. The device sold to chase teenagers costs between $300-500 so this is so much cheaper if that is your purpose. As far as bird again, I find it really does work. I have this strapped to a fence aimed over my driveway it so far with all the things I have done, no bird droppings. This device is best used with the power adapter which has quite a long cable. In my case, I am going to devise a way to run it on solar as not to deal with the batteries. The battery life is based of course on how many times it is triggered. Since people and animals trigger it, it can be going off quite a lot. Constant on, can only be done when it is on the AC adapter. OK, all said, I can say this thing does work for me. I actually bought two of them and I have not even needed to use the second one so far.

Ordered 2 of the Bird-X BG Balcony Guard a few weeks back. I was looking forward to setting them up and getting rid of those pesky Pigeons from my back yard and bedroom window area. Took them out of the boxes and got them working (I thought) right away. I placed one down stairs in the back yard at kitchen window hight and one on the bedroom window cill out side. I was woken up at 6 the following morning by those Pigeons once again, ok lets take a look, there might be some adjusting to be done. I removed the back from the unit and it was not working at all. I had to switch the unit off and back on again for it to work at all. Once it was switched on it automatically switched off and seemed to be ready for action but no matter what I tried, I could not get it to work and it has not worked since. Now the downstairs unit is not working and guess what??......yep, those dammed flying rats are back!! Think twice about purchasing these units if you do, I hope you have better luck than me!

My original review is below but, sadly, is no longer valid. These devices worked fine for 2 weeks but it seems the birds got used to the noise and are now back as bad as ever. While I once recommended these highly, I withdraw that view. I think our next effort will be one of those blow up clowns that flop around and attract attention to car washes. *************************************************** We bought this device to scare away the hordes of quail that were descending on us daily and making a big mess. We tried other devices that supposedly would keep these birds away. None of them worked. So, with a lot of skepticism, we decided to try once more never really believing that anything would help. Within 2 days, the quail stopped coming and haven't returned. We bought a second unit and aimed it in another direction and the birds stopped coming there, too. Even a squirrel that was eating plants in our flower pots disappeared. We haven't had any of these pests in a week now! The units makes no noise that humans can hear. I don't know about household pets because we don't have any. As for getting rid of birds, I remain astonished and delighted. I am writing this review because this manufacturer deserves a compliment. I'm giving this product 10 thumbs up! I'm a real buyer and no one gave me or promised me anything to write this review.
