Besmon Bird Deterrent Bird Scare Devices Keep Birds Away from Patio，Bird Reflector(16pcs/24pcs) High-Definition Reflective Double-Sided Bird-Repelling Device (24PCS)

I may update my review after this day. There seems to be a sparrow that enjoys perching for the evening on a planter hanger. I’ve been keeping the porch light on most evenings lately to deter it. After using this product today, I found the sparrow chilling on the planter hanger, again. Maybe I’ll give this device a little longer to work, then I can make an update if needed.Update: April 22, 2020After giving the product a chance to work, I decided to try another option. Even with the porch light shining and reflecting off of the disks, one bird seems to not be bothered as it sleeps in heavenly peace on my planter hanger.

THESE WERE SO MUCH FUN TO ASSEMBLE. YOU CAN PUT THEM TOGETHER IN A VARIETY OF WAYS.THEY ARE ATTRACTIVE ON MY PATIO. BUT, MOST IMPORTANTLY, THEY KEEP THE BIRDS FROMNESTING IN MY AREA, AND NO MORE FILTH ON MY CAR FROM FLYOVERS! I HAVE TRIED EVERYTHINGOVER THE YEARS; OWLS, CD DISCS, CHIMES, TWIRLY BARS. NONE WORKED. I HAVE THEM SPACED 3FEET APART HANGING FROM A BEAM. THEY'RE CERTAINLY MORE ATTRACTIVE THAN THE OTHERDETERENTS I HAVE USED IN THE PAST. AND THEY TOTALLY WORK WITHOUT CAUSING HARM TO THEBIRDS.

The bird discs have worked well so far. I had to put two together to get the length needed for them to hang far enough down from the pier ceiling so they would turn and reflect the light. Living near a lake, the birds, ducks, geese, etc., make a horrible mess. I’ve tried several ways to deter the fowls and these discs are the first thing that’s actually worked. Recommend.

I really didn't expect this to work, but it does seems to do what it says. The only down side is they are visible from outside of our windows, so as they rotate at night you get brief flashes of light in the windows. Freaked me out at first...but worth it.

I was skeptical, but these seemed to keep birds away and I even think they kept ground squirrels and other small rodents away. Easy to use and install and pretty, too!

A wonderful product to keep the birds from flying into our windows and harming themselves. I easily hung them outside in front of each window to protect the birds, and they look great.

Doesn't seem to work. 2 stars for quick delivery and because they easy to install.

Hung one with my weather station to keep birds away cause their crap was clogging the rain gauge cup. Working so far!
