I bought this and found that it is audible and unbearable to my young adult children. My daughter contacted the company, who explained that usually if it is audible, then it is a defective unit, so we wrapped it, bought postage and sent it back. The replacement unit is no better. I cannot say whether it works, since I cannot use it in this house without repelling the humans who live here.

I was very much interested in getting some of these 'ultrasonic' bug repellers so I took a chance on this one. These things are worse than useless! I have no idea if it works on bugs, but it would sure as heck drive me out of the house if I didn't un-plug it immediately. Seriously, I tried two separate units in different outlets around the house, these things emit a horrific sound that was maddening.

I purchased this product, about 2 weeks ago, in the hopes that this type of pest repeller had improved since the last one I attempted 5 years ago. This item has a thoughtful design, including a pass-thru plug (2 prong) and nightlight, and the innovative addition of an air ionizer that made placing this in a bathroom or closet a multi-purpose solution.

When I first plugged the unit into my downstairs bathroom outlet, my 2 cats 30 feet away in the living room started to growl and ran upstairs. My child came downstairs shortly afterward complaining about the painful warbling sound coming from downstairs. Apparently the ultrasonic frequency is outside of adult hearing, but adoloscent ears have a hammer and anvil response range beyond that of adults (until they're done growing, and the body loses flexibility, such as when the bones start to harden). I further tested the unit in the garage and an upstairs closet, but found the results were the same for both cats and family.

I am unsure of how pests respond to this unit, but it definitely repelled my cats and child, forcing me to discontinued use of the product.

If ever there was an advertisement for snake-oil, this would be it. We purchased this exact product and found the following:

* It didn't work at all. Saw a cockroach within the first 48hrs of switching it on. Had no effect on the rodent that was scratching away under our house either.

* The noise it makes is audible to humans and quite annoying - similar to that of a TV with a faulty tube. Our cat noticed it immediately and apparently did not like it.

Our rodent problem grew worse until one day it finally made its way into our house - right beside the Pest Repeller. Evidently it was not phased at all by the noise, the "high tech digital pulses", or indeed the fancy blue night light. Our cat, however, made short work of the rodent. I wish I'd spent the money on treats for him instead of this useless device.

In short, don't bother with this or any of the other products on the market. Consumer tests have since shown that high-pitched noises don't seem to affect rats, mice, or insects, so this is technically a falsely advertised product. Save your money. Get a cat. Buy a blue night light for less than a tenth of this.

If Amazon would have let me, I would have given it 0 stars.

I purchase this product because I was having a sever mice issue. I was catching them 2 and 3 at time every other day. That is too much. I have plug up the hole and they still seems to get through. I have to two children and worry about them getting bitten. So far since using the product I have not seen any mice activities within my apartment. I even put some of the dogs food on the floor and let it sit overnight just to see and there was non.

I am very happy with this product and it was worth the money. Because it has only been several weeks, I want to see how long this product last - that is my concern now.
