effective for a few days

Hung the balloons over a small block of cherry trees.  Worked on most birds for a few days.  Sparrow and robins weren't intimidated.  They did scare off starlings and magpies for awhile.  Next year I will try again and use the balloons in conjunction with propane cannons, grape Kool-Aid, and foil strips.

The smell of these deodorizers is overwhelming when they are first removed from the box they ship in and overpowered the restroom the first day they were installed. After 2-3 days, they lose some of their potency and add a faint, pleasant aroma to our small corporate restroom.

Our urinal is flushed 10-20 times each weekday and we're about halfway through the first screen after 3 weeks. I'm not sure they truly last for 2000 flushes, but a good deal nonetheless.

Pretty effective, although it takes a few days to affect it.  Sometime a little overspray or wind gust will cause it to kill sensitive adjacent plants. I use it sparingly, and wear full clothing (no shorts or sandals or t-shirts) to help mitigate any harmful effects.

My first impression was great. A well built product, robust, definitely not flimsily. Yes, it is bigger than what I was expecting, but in a positive way (the only drawback can be the electrical socket. You need a firm one to hold the product hanged there in place).

However, I was disappointed with its efficacy. It is not strong enough to eliminate the odors of rooms or bathrooms. Actually, it makes little difference even when at its maximum level (which makes a very loud noise). Therefore, after a couple of weeks, no one cares to turn it on anymore.
It seemed a great idea, though. I was really hopeful when I saw it at Amazon.

Seemed to work for a few days. Since we live on a corner property, the bottle was almost empty after just one application. Would consider purchasing a larger container if the price was right. Of course if people would be considerate and curb their dogs, this product wouldn't be necessary.

After having this product recommended by friends, I probably had high expectations.  I used the product as directed on the package only to have my little dog attacked by ticks just two weeks later - and I mean LOTS of ticks.  We used the second dose on time, since we had it we figured we should use it, and the ticks disappeared this time.  However, two weeks later, he had a flea infestation.  It seems that the effective length of the product is just two weeks instead of the one month promised by the product.  Since it worked for two weeks it gets two stars.  I'll be going to the vet for a different solution next season though.

Decided to try this out. I recently moved and only have a small patio for my two Shih Tzus instead of the yard they used to have. So, I've been playing around with options. The dogs took to the grass immediately and did their business. Worked great, but by the end of the first week, they were getting less interested as the grass started to die and get urine stained. I sprinkled some water on the grass every day to try to extend the green, but by around day 9 or 10 they lost interested completely and didn't want to go near it. Though expensive, I had thought about taking a monthly subscription (two per month) but not sure now. It would probably work fine for a single dog, but with two, it doesn't seem to work a full two weeks. Might try one more and see how it goes. Beats disposable or the hassle of washable pads, but I would almost need one per week, which would be very pricey.

This product works pretty well- after about two weeks of spraying it about every 2 or 3 days all around my apartment my boyfriend stopped having bad allergy symptoms (he's extremely allergic to cats). However, if don't keep spraying it really regularly, his allergies will return pretty quick. I think it says on the bottle to spray like every one or two weeks but it's only effective for us if I spray every few days or so. Either way, I'm still really happy that I found something to alleviate his allergies besides just a ton of medication.

The first few days.. I was impressed.  We have a pack of dogs next door that bark at all hours of the day and night.  We live close enough that I was able to place this bark controller close enough to be well within the advertised range.  Day 1,  sweet silence!  Day 2-3 ,  still pretty good!.  Day 4 I changed the battery because the dogs were barking again. Even after a battery change I was disappointed that it still didn't seem to annoy those dogs enough to quiet them down.  Maybe it was a bad battery?  So day 5 I changed the battery again.  NO luck.

Hoping to find a humane solution to quite them down.  This isn't it.

It keeps flies off dog's ears after applied, but I wish it lasted more than a couple of days without having to reapply.

Easy to set up and use, however, not very effective.  If an unlucky moth *happens* to come into contact with the adhesive it's game over.  There's no escape.  But the scent/pheromone use to attract them just isn't effective.  Going through a pretty bad infestation right now.  I've literally killed hundreds of the moths; these traps (four total) have killed maybe 2 dozen.  Yes, that's 24 moths I don't have to kill, but still pretty weak sauce.

This product is effective. After using it for just a couple of days the pest problems appear to have been resolved.

Recently had hundreds of the brown marmorated stink bugs hanging around our deck on the south side of our house.  I attached the trap to the deck corner railing in such a way that the bugs could easily crawl or fly to it.  I am rating 3 stars, one star for each stink bug caught in the trap after 2 weeks.

Note: I have also tried the dish soap solution and the rubbing alcohol spray methods both of which are effective to kill one or two at a time, but there were just too many and more kept on coming.  I finally had to call the exterminator who sprayed a time release insecticide.  It has been 2 days now and I don't see any live ones.

This worked temporarily, like the first few days that I used it with my dog. After a couple of days, however, my small dog figured out what was going on and then just ignored it, kept on barking. This might work for some, but it isn't a great fix and it did not work in the long run for me and my dog.

Okay, so this stuff worked pretty good, killed the many fleas, but my poor little chihuahuas got weird reactions. They both got extremely lethargic. One got a rash, and the other was foaming at the mouth and his eyes swelled shut. The one with a rash was fine by the next day but the other took several days for his eyes to stay open like normal. The foaming and their lethargy however only lasted the first day. But this has been the only flea medicine I've tried so far that has actually worked.

Reasonable shine and sprays easily but does not last longer than 3 days.

Very effective on discouraging the neighbor's dogs from barking.  They initially came outside barking (as usual) but after a while quieted down and just went back inside.  The episodes of barking became fewer.  I saw results in just about 3 days, which is very quick.  I recommend the Bark Stop Pos to anyone who wants a noninvasive solution to noisy dogs.
