I didn't get a discount or any free for a review. However I wish I did as I need more.I waited 32 days to give my review.I used two in my house which is a two story at near 4,000 sq. ft. if you count the garage.I didn't have a huge problem but had spiders, ants once in awhile but I don't like insects and I don't likekilling them. I don't know the proper name but I call them crab spiders. Very friendly little guys that would meetme at my front door daily around the door knob. They were not the target but after a few days they would meet menear the door frame and jump or walk out like you opened the door to let your dog out. They never came back. very cool.I had some spiders take residence in my basement bathroom and after 1 week they took the first train to the coast. The house isinsect free.I used one in my 35' x 25' wood shop. There I had field mice, carpenter ants, snakes, and everything else as it was built near the woods.Cleaned it out and prior for 5 years I had other ultrasonic controllers in there ( 2 units) and the bugs used them for a resting place. The mice, they laughed and it was music to their ears. In no time the place was vacant with just one unit. I love it. I would put a unit upstairs but did not have one.( explained later) I went to take my tractor out and I had carpenter ants running around on the patio and they came in the shop and I watched themstart to run in circles and they became sort of paralyzed. Very lethargic. So I reached over and unplugged the Cravegreen and waited a few minutes and they came to life and started exploring the garage floor. Then I plugged the unit in again and within a few minutes they were again spinning around on the floor and then started to once again become lethargic. I turned off the unit and when they came back to life they ran out of the garage. That really impressed me.The other unit went to my moms basement. Last one I had because she had all kinds of spiders. After about 3 days she told me that upstairs she was met with a large brown water spider at the kitchen door that when she opened it he ran out. I know the story is true because I experienced the same. Now her only unit was in her full basement and if you count the square footage of all three floors you are at nearly 8000 sq ft.So she needs at least two more so I will buy another four pack. I purchased units like these before and honestly they were worthless but they were not Cravegreens and the LED light is great for the bathrooms or kitchen.I remain really impressed. Money well spent!Update 10/17/16After three months of use I would still rate them a 5 stars. I can tell you that I have noticed a few pictures on here of spider webs on the unit.Excuse me for my limited knowledge of spiders but these units do not control spiders that have virtually no body. I guess the minute body does not allow these units to be effective. These are small bodied spiders but with long legs. I do not know what species they are. But the body is a size just above a number two pencil point. But these spiders really are not a nuisance like bigger insects. So in a basement setting these types of spiders are not bothered by these units. If it was in my budget I'd buy another box as I like them. In remote garages etc. the LED light looks like a security system. Another bonus. Thanks all!Update 3/5/17I had one in a garage and it did an excellent job. The garage was free of everything. Well last week even though the device shows it is working it has failed. I trap a mouse or two everyday and the months prior I had absolutely none. It worked great and now doesn't work at all.I will have to keep an eye on the others.

I have seen a significant reduction in pests. I use this in conjunction with EcoSmart Organic Pest Control Spray I got for $10 at Target. I sprayed that around my whole home inside and out about a month ago. Then I bought the cravegreens ultrasonic pest repellers. I got 8 of them to plug in each room of my home. I have a 3 bedroom/2.5 bathroom townhouse. I also live in the West Texas area so it's doubly important for me to keep on top of pest control. I had been getting my home sprayed about 2-3 times per year by an organic pest control company but hadn't received their services in about 8-9 months when I noticed an increase in mostly beetles and spiders. Then, I found the biggest black widow spider I had ever seen in my outdoor trashcan. I immediately bought the spray from Target and the ultrasonic repellers from Amazon. I immediately noticed a significant reduction. I see some pests every once in a while, but by the time I see them they are usually dead or close to dead or stunned out of their mind by what I am assuming is the ultrasonic repeller. My family members live in the county in the eastern area of Texas and also have issues with pests so I bought the ultrasonic repellers for my grandmother as well. Whether you live in a house, an apartment, a townhouse, or a condo, maintaining pest control is a necessity. It is better to be on top of the situation than to have to fix a horrible problem later. Thus far, I would give this product 5 stars. I went quite a while in between treatments (my fault) and was seeing a few pests every day (nothing crazy or horrible -- my home is pretty new) and now I see them very rarely if at all.

I was really hopeful, I thought $40 is a small price to pay to be rid of the insects in my apartment, but these just were not effective at all. We moved into our apartment a little over a year ago, and we shortly discovered we had issues with some flies, fruit flies, small roaches, spiders, and later mosquitoes. I had a bug zapper that was both very effective on the insects and also kinda fun to use, but once we started getting some mosquitoes I wanted something that would effectively repel them, especially since we have a baby daughter. I looked into these ultrasonic repellents, but never got around to deciding on one until about a year later.This summer, we started getting ants in the apartment for the first time since we moved in over a year ago. We believe it was due to the extreme heat, and I decided it was time to finally try these ultrasonic repellents to hopefully take care of the ant problem before it got worse. Taking care of the other insects we've already been getting would be a plus, the thought of finally living without those pests was nice.Based on the reviews, I chose Cravegreens' product. I don't know what the square footage of our apartment is, but it's not very big, two bedrooms. I felt like less than four of the repellents would have been effective, but decided on the four pack if it would help even more. I was aware that it could take two to three weeks for them to really take effect, and that within the first few days the number of pests could even increase.Unfortunately, a month later and they never really seemed to have an effect. We were still getting the flies, small roaches, spiders and mosquitoes. And the worst part is, the ant problem only got worse. They seemed to have established a colony in the walls, and winged ants started to appear. Those are a major nuisance, so I decided these were truly not effective and it was time to request a refund. I really wanted these to work, but sadly they didn't. So much for being the "best repellent for cockroach, rodents, flies, roaches, ants, spiders, fleas, mice".

Bought these in 2018 for spider and mice. Worked amazing and I liked it so much I brought them to my other house in 2019. And brought them with me again when I moved in 2022. Still working. Highly recommend.
