Ultrason X, 110v

Excelente equipo 👍

My work installed these after we had an infestation of crows & baby crows, pigeons and sparrows. It runs every 10 minutes through a variety of bird sounds. No more birds.Just wish it wasn't so expensive so my employer would buy more and install it in other areas with bird problems.

I had an infestation of common house sparrows and was at wit's end trying to figure out what to do. I'm a writer, and need quiet to ply that trade. House sparrows are blessed with arguably the most annoying chirp of any bird that flies, and my bunch felt they had a mission from God to perch at my window and irritate me to the point of tearing what little hair I've got left on my head - never mind the mess they left behind! I purchased this gadget based on its written promises to rid the planet of all things 'avian.' Bogus. Yes, it does indeed broadcast a truly impressive ultra-high frequency sound wave, but instead of shooing away the little pests, it ATTRACTED them! The next morning I actually had pigeons perching on the table with this thing (note that I have NEVER had pigeons at my house or any problem with their species. I then picked up two of the speakers and pointed them directly at a dove pecking on the ground less than 10 feet away - it just looked at me like I was stupid and kept right on feeding, and I'm not making this up or embellishing my account. There were birds flying over to see it instead of running away. I turned it off and cleaned up the bird poo, then sent it back.With the neighbor's permission on both sides of my house, I climbed up and stapled fiberglass mesh over evey hole on their roofs; yanking out the sparrow nests and mess. I then purchased a "Deluxe Repeating Sparrow Trap" available at [...]. Folks, this thing WORKS - and I mean it! I've never seen the like for doing exactly what it says it will do, and that is to trap live any and every one of the little monsters (the inventor/owner explains several methods to get rid of the sparrows). I stopped counting after 35! It also caught two Desert Wrens and one small Dove - which I released. The price is reasonable and you will be impressed with the number of highly satisfied customers who have taken the time to write and praise this product. Ahhhh, quiet! Hope this helps you as much as it helped me. Knightsix

Good

Birds continue

don't work

on time and good item

The dreaded ravens sat right next to it, undeterred and not bothered. Ravens are territorial and when they see reflections in windows they think they are interlopers and attack the pane. If you can make the reflection go away, they will go away also.
