Bird Chase Super Sonic - Outdoor Sound Repellent - Scares Away Birds - Durable Weather Resistant Design - for Large Open Outside Spaces - Programmable Device - Up to 1 Acre Coverage

Woodpeckers are the bane of my house's existence (redwood shingles). I had previously tried everything! Every 10 minutes (I set for daytime only) the woodpeckers, which are federally protected so I can't go all "Elmer Fudd" on them, get warned away by woodpecker predator noises and woodpecker distress calls. This lasts for about 20 seconds at a time, and you can control the volume. My first one lasted only one season, and would not start up the next spring, even though it had been stored in a warm garage with no power to it all winter. Doesn't matter, though. I would by a new one every year (especially at Amazon's prices) if I had to. Definitely worth it.

The speaker works just as described, it makes all kinds of bird noises and it is very loud BUT it doesn't scare the birds away. After 6 months of use on my backyard I still have a bad case of birds sitting and pooping from a tree into my patio deck which makes it impossible to use. The device is priced very high which led me to believe that it would be the solution to my bird problem, but after trying different settings, volume levels etc, the birds don't care about the sounds the device emits. I installed the box a couple feet away from the tree and the doves and pigeons still land on the tree and relief themselves and sleep on the tree at night. Waste of money, doesn't scare birds away.

We had some woodpeckers pecking at our cedar shingles and siding. I bought this and no more woodpeckers! I have been pleasantly surprised by how well this works (so far, about three months). Two days after we hooked it up, my son inadvertently shut it off by unplugging and plugging back in (see flaws). The woodpeckers came back later that day. Reset it, back on, no more woodpeckers. There are two flaws that prevent me from giving it five stars. 1) If it is unplugged, or loses power for any reason, it will not resume when power is restored. You have to manually reset it. It's very easy to set, but if you go out of town and there is a brief power outage, it will not function until you get back home and reset it. Not ideal. 2) The 12V power supply that came with it quite working after a couple weeks, creating intermittent problems. Fortunately, I had another (better quality) power supply that I was able to use with the unit and it has worked flawlessly ever since. This would probably force most people to return it.

I live in Phoenix Az and we had a pigeon problem since my stupid neighbors began feeding them next door. We have a pool with beach entry and the pigeons used it as a bird bath. Anyhow I ordered this bird super sonic device and set for daytime and pigeon setting and in the first hour pigeons were gone. However being that they are homing pigeons they did not go far and as soon as I turned it off they cautiously returned. So next day I turned it on again and set it along rear fence walk facing my house and angled slighty at about 30 degree angle, not sure if it made a difference, but wanted the sound to be directed toward the roof. Anyhow, i kept it plugged in and on for a few days and the birds moved to a house 2 streets behind us. I went ahead and left it on for a full month and believe it or not there are no pigeon anywhere within my neighborhood of around at least 1/4 mile. No joke guys!!! We had a new roof installed and I did not want these rats pooping om my new concrete tile so this is why I bought it. One of my neighbors did complain about the noise cause it spooked his dog but this was the same dumb Johnny Apple Seed $@!#% who was feeding the pigeons in the first place so I told him to STFU. Anyhow it also attracted some real hawks which may have actually helped. It has been about 10 months since the pigeon left and they are still gone. The other reviewers must not be allowing this time to work. It really does. I will try and load pics of my roof and neighborhood to show that there are no pigeons anymore. We do have crows but they don't bother me at all.I could use the crow setting if they did. I recommend this unit 100%. Just be sure to place in shade or the plastic clear cover will yellow slightly. No biggie it still works. I will keep and if those pigeons ever return I will plug it in again. But I don't think they will ever be back. Yes!!!!

I tried everything to get rid of the Starlings that turned my pool cover into a filthy bird bath. These birds have no fear, they would land on the side of the pool 2 feet from us while we were swimming. All the other birds were gone because of these bullies of rhe sky. I tried owls, which I moved daily, snakes, a rubber alligator, a spray (which sorta worked if you sprayed it 2-3 x daily) The birds would just laugh at me and continue to poop everywhere. Then I bought this device. I really did not expect much. But I plugged it in. Saw a pigeon on.my fense, so set it to pigeon, the device played and the pigeon flew away. Hummmm. Ok. Then I set it to Starling. And since that I time I have seen just one starling, it landed in.my yard far end away from the device. So I turned yhe device up a bit, and I haven't seen one of those nasty birds since. My pool cover is clean. No more birds hanging out and pooping everywhere. TBH we found the noise weird at first, but within a few days we just leaned to live it, and it's no big deal now.

Only one speaker worked . If I had not needed them so bad due to many birds I would have returned them but I ended up using one speaker. The other speaker just makes a muffled noise. Not impressed as they were expensive considering I only have one .
