DANGZW Ultrasonic Pest Repeller, Indoor Electronic Fly Repellent Plug in Pest Control for Cockroaches, Mice,Ants, Mosquitoes,Ultrasonic Rodent Repellent 100% Harmless to Pets and Human(2 Pack)

Nearly a week using it but I haven't see any improvement on the area in the house that I bought it for so maybe it does need more time so fingers crossed that it would do what does says in the package and post on AmazonA year afterwards and still not doing their job. How long more I need to wait for. Been switch on for over a year so it does cost me money but it doesn't know do the job.

I got this product in hope it would help stop fly’s in my kitchen. The flys don’t seem to care, even a week or so in.To top that, and show how useless the product is… the cheeky spider decides to build a web attached to it! First pic. Now a few days later, either the spider has grown crazy quick with all those decibels OR the other one told it’s mate about this cool new spot. Just to add, the blue light is really annoying and unnecessary. I’ll give it another few weeks but definitely would not recommend at this stage…🕸🪰

Trying to get rid of flies is a nightmare so thought we would try the 'pest propeller' as many had indicated that it did the job. Unfortunately the two plug ins didn't work for us and and didn't deter the flies so am unable to praise its usefulness. Sorry!

we have been using 2 x of theses in our new conservatory for nearly 1 year. These do work up to a point. recommend during summer months to have them on 24 hrs a day-not needed in autumn/ winter. We noticed that there were much less flies coming in (when doors completely open) during late spring/ summer which is only when we have them switched on, but do still get a few flies, just not as bad which i guess is to be expected. Thet do NOT stop nats- we bought 1 x citronella candle to prevent these on the summer evenings which works. We have found we only need the fly spray very occasionally unlike before. The plug ins appear to only stop certain flies coming in but are worth the money if you live in a quite rural area like us.

I bought these when I noticed ants coming into the kitchen. They’ve not been back. But also the conservatory is usually full of flies and wasps in the summer. It just hasn’t been, any fly or wasp or bee has left quickly. I’m leaving this review because I’d read so many poor reviews I was doubtful but I’ve just ordered some more for my son they’re so good. Tbf we don’t have an issue with rats or mice so I don’t know how they’d be with them and there are still a few spiders around ( I don’t mind spiders).

I hoped these devices would be effective against flies but they have absolutely no impact on flies coming into the house. The only thing they do is use electricity and look pretty in the dark. Not impressed at all.

These are Absolutely Useless I assure you Amazon buyers one and all, I received the 4 I'd ordered, simply plugged them in and waited. So it's well over 3 weeks now since they've been running/installed here, and believe you me, they do not work at all, and as bizarre as it may sound, I actually started getting even more small black flies than the ones I'd already got and were trying to scare off, as it were! So I unplugged them all and have thrown them away now, but guess what, now even the new lot of flies I'd had after using these, as instructed, have since gone away too, Crazy or what!!

My granddaughter hasn't seen any more spiders to in her bedroom easy to use just plug in and forget about it and obviously leave turned on
