In contrast to several other reviewers, I'll be out front: I purchased this to address a ROACH issue I was experiencing in my condo. especially in the cooking area. A brief recap: This item functions! Understand it. Since I bought it three months ago, I have not seen a single roach. I wanted to make it clear because many product reviews and descriptions lacked specificity, and it's possible that reviewers are embarrassed to acknowledge such a widespread yet unpleasant issue. I had to be certain because I was desperate. I want to reassure you—even if you might be desperate—that this is real. Extended Review: Since I always assumed that ultrasonic repellers were some sort of fraud, I was really dubious about using them for this particular issue. I reasoned that, as mice are mammals, it would, at most, probably work for them. But most definitely not for bugs and insects. And I was not. After three months, I can now say that this product was the difference. I had great success years ago maintaining two places I had resided in at different times free of roaches. Furthermore, I was positive that my neighbors at that time were


I didn't think something like this could possibly succeed. I recently purchased a 1963 house that has a locked attic area where a few furry guests periodically stay. I hear them crawling around in the corners of the room around the fireplace and in the spaces under the eaves. When I turned the TV up loud, they would frequently stir. I consequently purchased the Neatmaster Ultrasonic Pest Repeller. The most I could do, as I mentioned, was to place the repeller in the spot where I heard the activity because I am unable to enter the attic space. The manufacturer advises against doing this. Still, it's the best I could do short of drilling a hole in the ceiling. The moment I switched on the device, the bats began to scream and stir. I didn't like the human audible sound it produced in the setting I had it at. (Cyan) But until the animal or animals ceased making noise, I sat and listened. I think it went out. I turned the gadget off at that setting for the night. I adjusted it to the "Green" option, which is neither audible nor less so, the next morning. I've left it in my living room in this configuration.

My initial impressions of this ultrasonic pest repellent are as follows: 1. The item was delivered on time and in perfect condition. 2. I took it out of the box and plugged it into the wall; it doesn't go through walls and functions best in wide spaces. 3. Since we have a small insect problem (we live in the basement, therefore there are often a ton of spiders, crickets, spider-crickets, etc.), I chose the green setting. 4. I then bided my time to observe how well it functions. I saw an immediate difference in the quantity of pests! Every day, I see at least two creatures on average. After connecting this device into the wall for a full day, I had not even spotted one bug! I believe I only saw two bugs in the first week! FRENTY! If you're anything like me, you detest eliminating harmless pests; I've never been able to destroy them. Whenever I see one, I either try to catch it in a cup and bring it back outdoors, or I just sit a cup over it till it dies and discard it. I would even occasionally spritz them with hairspray. But I'd prefer not to murder them. Thus, as you can expect, t
