Bird B Gone - Reflect-A-Bird - Reflective Spinning Deterrent - Repels Pigeons, Sparrows, & Woodpeckers - Wind Powered - for Gardens, Railings, Roofs, Etc - Weatherproof Aluminum - Adjustable Neck

Bigger than I was expecting. Looks well made.Time will tell if it keeps the birds away.

I installed these on a rooftop on a college building, it has been there, doing its job for about 6-7 months. the building used to have a lot of pigeons around, I applied other techniques combined with the use of this and it has been working really good.effective.

I got this knowing the reviews were not so good and a lot mention it not spinning.I ordered anyway thinking it can't be too hard to fix if there was a problem.I got it and removed it from the box. Immediately I noticed it was binding when I spun it.There was no way it would even spin with a breeze. Since it only had 4 screws and looked simple, I decided to takeit apart to trouble shoot. As soon as I separated the spinner from the bearing you could see the problem. They used a standard sealed bearing. The problem was on one side, it looked like someone took a hammer and screwdriver to the bearing shield and dented it all in on one half. Since it was dented in on one half, the other half was raised. The raised side was rubbing against the retainer clip preventing it from spinning freely. The stand is nice and solid, the spinner is chromed plastic (as I expected). The only fault was someone jacked up the bearing. I will return for another one because Im sure it will do the job. The question is, how many will I get before I get one that is functioning correctly. I don't have the option to add a pic here, but will try to add one after I submit this.REVIEW UPDATE: seller replaced item immediately, great customer service. Attaching a picture to show that this device does not seem to faze the cactus Wren

I installed one on each corner of my home and the have done a great job on deterring birds on my room, quick and easy setup

I bought 5 to put around my house, I am not sure yet whether these really work but I am hopeful, since my neighbourhood has a real issue with bird nesting in properties.

Worked perfectly

What's more annoying than some dopey bird pecking at your roof at 6:00 AM? No longer do I find myself outside squirting the little twerp with a hose to drive him off. This is particularly true of the lovely desert woodpeckers that poke holes in anything that's stationary for more than 3 seconds.I bought this item with little hope that it would work. To my surprise, it does! Now... for it to work, it has to move as woodpeckers, apparently, don't seem to like shiny moving things. When the air movement ceases, the effectiveness drops. Since we live in the desert Southwest, flat roofs are common and there are few places to affix these to where they would catch the breeze. My solution was to mount it in proximity to the air stream of the fan on our roof mounted heat pump. When it's running, the reflector rotates... which is what deters the little twerps in the early morning hours as the heat pump is either running to heat or cool at that time of day. The rest of the day, it's breezy enough for the reflector to spin on it's own. Oddly, spooking the woodies has also reduced their desire to destroy our orange crop... a nice side benefit.Now, if only I could find something to chase off those dopey Mourning Doves that use the entire world as their toilet.....

worked and was easy to assemble lots of different ways to mount it.
