Bird-X BG Balcony Guard

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 productSince, 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.

Product was of poor quality. Did not fulfil functions that it was meant to do.

Desafortunadamente no funciona... no digo que el aparato o sistema esté defectuoso, quiero decir que esta solución no funciona contra las aves. Tenemos golondrinas anidando año con año, como pueden ver, ni el búho ni el repelente electrónico han logrado su cometido. No sé de aves, tal vez las condiciones que aquí encuentran, son mucho muy agradables para anidar, pero; a menos que cubra todo con malla sombra, no veo que éste u otro aparato similar pueda funcionar. El aparato está en perfecta condiciones, los materiales con lo que lo fabricaron se ven de muy buena calidad.

We have been troubled by House Martins nesting in our open garage; I had already tried steel netting on the purlin and so was pretty desperate.The item looks like something made up at home from bits bought at Radio Shack. I wish I had seen the research that suggested that birds are troubled by ultra-sonic noise, as my friends must be deaf. If it works at all then, if you can hear the sound, perhaps maybe some birds can also.You twiddle a knob at the back until it is at its loudest. Being an enclosed space you might expect this product to work better. The IR detector can see me approaching pretty easily but while set in this mode, every bird in the neighbourhood seemed to visit, presumably without triggering, so it is now set permanently on. This means that we have now only the odd 6-8 birds messing up the cars.Over time the pitch of the noise changes so it needs to be adjusted frequently. If it were £20, it might be worth a punt; at this price it is just too expensive to try.As a back-up plan, I also bought a large decoy Falcon; that is not effective either.Perhaps birds are just not as dumb as we humans are gullible.
